BIAB won't regenerate specific measures; only the whole song (but can regenerate a whole single track by freezing the other tracks). But not specific measures within a track.

One option is to use RealBand, instead. It can load your BIAB MGU or SGU file directly, and then you can highlight specific bars on a track or multiple tracks and regenerate just the highlighted portion.

Or do as you are currently doing by slicing/dicing within the DAW of your choice.
