I'd like an option to go back and continue refining after storing a profile. That way if I get to a point where I'm not sure if further refinement will mess up a profile or improve it I can take a snapshot then carry on from where I was, maybe quickly knocking out versions for Rhythm, Lead and Quiet/Dynamic usage. Otherwise as it is right now you have to traumatize everyone else in the vicinity (and yourself) by starting the profiling process again from scratch and you can't carry on from exactly where you were.
Edit :
It would also be great for those situations where you only realize a short while after the event and you've tracked a couple of takes that it's close but not quite right and needs to be refined further (rather than completely redone). In that case you could go to the refining stage on a profile that's already been stored. Instead of just being able to jump back to the last page of the Profiling process where you can refine after clicking the Store button.
