Along the lines of the above answers, take a look at the Window menu. You will see:

Chord Substitution Dialog
Auto-Generate Chord Substitutions
Chord Reharmonist Dialog
Auto-Generate Chord Reharmonization

This is the way it looks in BIAB version 2014. The chord substitution has been in BIAB for over a decade at least. You enter a simple chord progression and it will suggest alternatives. Some are quite advanced. Very powerful tool.
