When I made a song with a simple arrangement of 2 chords Am9 and Dm9 saved just the band then a new song with Cmaj7 and Fmaj7 and only generated the solo, then put them both in my DAW it worked just fine. You might try the same with chords that contain the same notes as your progression and get results for Dorian mode. I'm not a chord wizard so don't know which chords to replace with what you are using, but I bet someone here could suggest them if they knew your progression. It won't be an all at once Biab playing thing, but it might be a work around. (Maybe)
