Feature request: midi control metronome time signature

It's a small thing, but it would be nice to be able to control the time signature with my external midi controller rather than point, click, look etc. 

When I am practicing I switch pieces and they all have different time signatures.

It might be weird to assign a cc # to something that isn't an ordered set, but I don't think it will matter.  I don't mind scrolling through the different time sigs.

If this isn't the right place for a feature request, could someone let me know?

Thanks!  PT is wonderful, so is the metronome, just want to avoid a little step in my practice.
