I think I have a solution
I don't do it in BIAB.
Truthfully, I don't know how to do it in BIAB.

I do use BIAB to create all my tracks.
I export .WAV or .MP3 files from BIAB.

I use Anytune Pro for performance. It has a variety of features you may like.
The looping part is what you use to control the number of chorus's played.

Here's a 2 minute presentation that provides the gist of the approach.

The bluetooth pedal the presenter describes works great but I don't think its absolutely required.
It makes it a lot easier. I for other features also.

Its not a BIAB solution but it works on IOS or Mac.
I use either a tablet or my iphone. Both work great.
I don't have to bring a Laptop to the gigs.


It may not prove satisfactory to your needs but I believe it will accomplish your objective.
