The thing is, BIAB reserves the right to voice chords as it sees fit, depending on style and instrument, so even if they included “add9” in the roster, it would just be a synonym for “add2”.

I do like the idea of a “high slash chord”, though most styles will have a bass line to handle those slash notes, whereas there is nothing like a corresponding “high line”.
