RealBand is not BIAB and there is no quick fix. However, you can set up your Seq file to improve your review situation. If you have not done so already, use Tracks > Make first 8 Tracks BB Tracks. Then Highlight a section of the first BB Track for say 32 bars only and then extend the highlighting to all the BB Tracks.

Open the Styles Window and use Search facilties to find styles in the genre you require and select style - Select Generate Icon - Select BB Selected Region, Selected Tracks and your tracks are created.

This is relatively quick and you can regenerate individual tracks by using the various other options available. When satisfied, generate the full track length.
