Another approach: now that it is possible to construct your own RealTracks (called UserTracks), you could take that 2-bar clip you like, replicate it, and make it into a UserTrack.

Or, you could make it into a Loop file. BIAB can use those, too.

Of course, either action uses BIAB as a strict sequencer, something a DAW could do, since it eliminates the randomness, or artificial intelligence that is varying the backgrounds. Remember what BIAB was designed to do: provide accompaniment, in as realistic a way as is possible with a computer.
