I couldn't believe that the Mac version wouldn't write the part markers to the midi file as markers, so I tried it and yea it don't ! I use that all the time on the Win version.

I import Biab chords into Reaper via musicxml export from Biab.
Then get the part markers via midi export.
I know it's easy to insert markers in Reaper press M at the cursor, you can even create action to place a part marker A or B every so many bars.
Not sure if this would help:

EDIT: Also you can upload any SGU MGU and I or someone else with BBWin will save it to midi with part markers. If you want chords in the midi file I can do that also or you can get Reaper and it's free to try n try n try.. and it will write your BB chords to midi markers.
