What about entering Am7b5 ? That should give you the C natural and the D# as well as the 7th (I don't think there is an Adim7 available)

Are you referring to the dominant 7 (G note) or the natural 7 (G# note)? Assuming you're referring to the commonly used diminished with a flat 7 (dominant 7), use the m7b5 spelling as shown in your Chord Builder. If you're trying for the classical diminished with a scale tone (natural 7) then I don't think you can do that in Biab.
When constructing a diminished seventh, the ‘seven’ is double-flatted. This continues the series of minor third intervals. So Cdim7 is C, Eb, Gb, A. The A is Bbb enharmonically. No, that’s not a typo. Thus there are only three diminished seventh chords before the pattern repeats.
Some years ago when we discussed all this, I believe that it makes a difference what style you are using, whether BIAB will play that double-flatted seventh.
If I recall correctly, either in Preferences Arrange or maybe Display Options, you get a chance to specify how you want this chord to look.

So did those above responses answer your question satisfactorily?

[size:8pt][/size]Thanks, Mario. I wasn’t at a computer, but that’s the one. It’s quite a powerful checkbox, more like a preference than a display setting.
Remember, it may not give you the dim7 if you are in certain simpler styles.
And say happy birthday to your wife. It’s been nice knowing you.

Which makes for interesting possibilities for key modulation. I mention this because I found it very cool when someone told me about it a long time ago.
Since Adim7 = Cdim7 = Ebdim7 = Gbdim7 (i.e., these are all the same chords), having landed on any inversion, you stand in the same harmonic relation to four different keys.
So, if you start in C major and find your way to a Cdim7 chord, you can say, OK, now I'm in A major, and take it from there. Then you can find your way to an Adim7 chord and switch right back to C major – or Eb, or Gb.
I recorded this 28-second thing back in 1981 using a Casio VL-Tone, to demonstrate!
OK, here we go again which was predictable. I'm not classically trained, I'm basically a rock/blues/jazz player starting in the 60's. To me a dim chord when put on a chord chart is a 4 note minor 3rd interval chord, and yes there's only three of them. Never have I seen what is intended as a dim chord written on a chart as a dim7. I would read a Cdim7 as a m7b5 or half diminished. IOW, a dim7 means one flat or dominant mot a double flat. That's because if the author of that chart wanted a standard dim chord it would be written as a Cdim. This is from thousands of fakebook charts I've used over the years. I understand that classically speaking it's a double flat but it's not common usage in my experience which is why I asked what the OP intended.

If I were writing out chords, I would just call them "diminished," but I believe it is musically correct to call them "fully diminished 7th" or just "diminished 7th" chords, and I believe this is a common way to abbreviate that.
The 7th interval in a "half-diminished" chord, after all, is minor, not diminished.
Jeez, this stuff gets in your head... I was wondering about this variation on the 7th, and what it would be called, and here it is, with its own Wikipedia page:
Mark, that’s the one thing I’m pretty sure is NOT right. That link is a Major seventh diminished chord.
Right, I'm just checking off the possibilities. There are three kinds of 7th intervals, major, minor, and diminished, and sticking those on top of diminished triads gets you three "diminished plus 7th" chords. This one's the funky duck of the bunch.
I think we can all agree that there is no agreement. We also can agree we are not sure what the original poster (who is new to the forum) intended, since we haven't heard back.
I don't understand – what's to disagree about? I really don't see this as a controversial subject. Some use the term "diminished chord" to mean "fully diminished 7th chord", and regard the abbreviations "dim" and "dim7" as interchangeable. If some do not, hey, freedom.
