Welcome to the forum. You are looking for a feature to generate and insert modulations.

I congratulate you because to my knowledge no one has requested this before. You can insert bars, and you can insert a new key signature, but you now have to write the chords to accomplish the modulation. This would be nice to be able to ask BIAB to construct that and specify the starting point and duration.

Although BIAB has an Undo feature, it would be important to make sure it works for this feature.
