When exporting your project, not as music xml, but as a midi file, you have the option to include the tempo map, chords and sections (as markers), lyrics, and other midi metadata:
I would imagine that the beat detection in SMP can probably do something similar. (you should check that out to streamline the workflow).
Wow, that was easy... and it gets better! Not only can we Export as midi with tempo map, then drag the midi into Reaper and tempo map appears immediately but we can include all the chord labels!! I have got to spend more time with SMP!
