Hi,
Is it possible for BIAB to come up with really jazzy arrangements from straight chords?

For example, take Amazing Grace. It only uses G-C-D(7)-Am. Can BIAB add tensions (such as GM7, C13), or change to C on G (not just inversion...what are these called?), to these straight chords, and make jazz accompaniment versions of Amazing Grace? Is there a magic button to make it happen? That would be awesome!

If so, is the melody line input required?
Thanks.
