I've also asked for this multiple times. sus2 and sus4 are supposed to replace the third with the 2 and 4, respectively, not add the 2 or 4 to the chord by including the 3. This also gets to be important where a song (and I've seen several examples) will do a Csus4 (or just Csus with the 4 implied), C, C2, C...so you can hear the movement within the chord of F to E to D and back to E, and variations thereof.

And of course, the add9 is supposed to do just that to the major chord, omitting the 7th you get with, say a C9 chord (C-E-G-Bb-D); the Cadd9 would be C-E-G-D (above the G). Likewise, the add2 would be more of a close chord by inserting the 2 between 1 and 3 (C-D-E-G).

As someone who uses this a lot, this is definitely something I wish would get fixed. I do know that sometimes it gets it right, but that's more a factor of the randomly selected parts of the style, where the 3 might be left out of a particular riff defined in the style or RT; but other times the 3 gets put back in.
