You can already do chord substitutions in BIAB. You can generate an entirely new chord progression for a complete song or a portion of a song.

You can also create your own chord substitutions by editing the file CHORDSUB.TXT (I believe the file contains directions on how to do it and the user manual talks about recompiling your own substitutions.

See page 396-400 in the PDF BIAB 2016 user manual for more details.
