This has been my workaround for a few months now but it just gets a little tedious when wanting to just explore a multitude of different saved MIDI progressions. I'm usually not committed to the first progression I import so when I want to try a different MIDI file that I have saved, I have to repeat these steps all over again.

Open BIAB -> Import Midi -> Save to SGU -> Open DAW -> Open BIAB VST -> Import SGU

It be a lot easier to just "import a midi file" into the VST
