currently clients can only rate the overall workout

but what if they find one exercise quite easy (say, RPE 5) and another quite difficult (say, RPE 10)

now they can type this out in a separate chat or add it to the comments, but that's not very convenient especially considering they'll be in the middle of a workout

So why not have a feature where after they complete their final set of any given exercise, a screen pops up with a sliding scale asking them to rate the RPE for that exercise (i.e. for the last set)
