Donny,

I have a couple of "Fake Books" and it is very easy to just type the ghords into the bars of BIAB. You can do a different chord on evey beat of the measure if necessary. It has a very nice feature of having the pedal bass playing the 5th note of the root chord on turn-arounds on the 2nd and 4th beats as many a jazz recording uses. I haven't heard an arranger that does this yet, that I know of. and the feature is a click or two away.

It would be great for playing your accordian along with on swing tunes too. It also works great on Dixieland tunes. My improvisation brain kicks in at these turn-around licks by the pedal bass. Man what a grove if you dig the jazz standards. Heck I even do it on the country tunes that I do.
