Here's how BIAB treats these. I've included some of the built-in shortcuts, as shown in the file, /BB/Data/pgshortc.txt

Note these are already defined in BB, and you can't over-ride these shortcuts
;sus2@2 add2@2 m+@m#5 dim7@dim 7aug@7+ sus4@sus 11@9sus 9sus4@9sus
;13sus4@13sus add9@2 7sus4@7sus s@7sus h@m7b5 d@dim J@MAJ7


Note: sus2 means 2, add2 means 2 and add9 means 2. They all map to the same chord.
