if such a feature existed, I envision it working like this:

1) In BIAB, you might right click on one of the instruments at the top of the screen, and a new option "new tab" would be available

2) when you initiate the "new tab" function, the tab name would be the patch assigned to that instrument


In RB, it could be similar, except you'd access it by right clicking on a track, which would mean that track gets its chords from the new tab
