I have a (somewhat) similar experience on a smaller scale. I had this idea I could break a complicated score into the individual tempo parts, and reunite them within a setlist, and then the software could scroll at different tempos in different parts of the score. This works fine, but then, like the author mentions above, I can't nest this setlist as a single entity within a different setlist. Instead, I must put each individual section of the subdivided score into the setlist. Not the end of the world, but the nesting of setlists within a setlist might be an idea worth exploring.
