MIDI Position Markers

[Keith Smith]

Is there anyway to generate MIDI Position markers in the MIDI output?
My use case is that \unfoldRepeats only works for simple "\repeat volta 
...{" constructs.  In compositions that have D.S. Coda, etc the 
structure of the composition is lost in MIDI.  I import the MIDI from 
lilypond into my DAW (Reaper) and then cut and paste to get the 
structure back.  My DAW will also import MIDI Position Markers if 
available.  If I could generate these directly from lilypond then it 
would be very useful as I would be able to find where I need to cut and 
paste the lilypond MIDI  in my DAW.

Thanks,
