I don't BIAB in front of me to figure out an elegant solution, but a brute force solution might be:

1. Open your song (no embellishment).
2. Turn on light embellishment and hit play (so the notes get regenerated) and make sure you're happy with it.
3. Make the embellishment permanent.
4. Export to MIDI (i.e. myfile_light.mid).
5. Without saving, open your song again (no embellishment).
6. Turn on heavy embellishment and hit play (so the notes get regenerated) and make sure you're happy with it.
4. Make the embellishment permanent.
5. Export to MIDI (i.e. myfile_heavy.mid).
6. Without saving, open your song again (no embellishment).
7. Import the myfile_light.mid, but select only the bars you want to include and only the melody channel with the offsets where chorus #2 starts.
8. Import the myfile_heavy.mid, but select only the bars you want to include and only the melody channel with the offsets where chorus #3 starts.
9. You should now have what you wanted. Save the file (maybe to a different name) to preserve the changes.

This may not be the exact process, but hopefully you get the idea. My guess is that it would take all of 3 or 4 minutes to do this (probably less time that it took me to type this response).

Let us know if it works.
