Of course I can type it in myself. But that would waste a lot of time.
There's a method of note entry recommended somewhere, where you record note timing by tapping out the rhythm on one key or pad and then use the notation editor to step through the notes in notation edit mode, with the cursor keys, adjusting the pitch up and down using the cursor keys. It's fairly quick, though of course not as quick as playing the notes or BIAB doing it for you.
I fully understand that you want one note only, but I'm not convinced
personally that the "Chord Track" is the best place to do that.
I note that Mark Hayes disagrees with me in the other thread, so maybe I'm wrong.
When doing my own design work for hardware and software I try to keep things neatly partitioned and consistent. I worry that making a track specially devised for sending chords become a track that does
not send chords in some circumstances will result in confusion and bugs. My concern is to do with the rationale of the code, especially when ordinary MIDI tracks can already easily send one note at a time. What you want, I believe, is to
send one note at a time and specifically the root or slash note, whichever is the lower pitch.
I'll not say more, as it's a decision that must be made by PGM. I express only my personal opinion about it.
