FWIW I'd use Realband for this.
It lets the same style be used over different time signatures better than BiaB in my opinion. Including the use of Time Signatures not even allowed in BiaB (7/4 etc).
You wouldn't need to change styles, just change the time sig for the desired bar(s) and change it back to original after that section, then regenerate.

just a thought
YMMV depending on the style.
