You can convert them to Yamaha STY PRS that are just midi files with section markers if you rename to .mid
I tried the Biab midi to STY converter but it was very old and had many issues when trying to create a multistyle from the Yamaha midi styles.
So I just asked again for MidiUserTracks as it would solve this issue.
