Exercise difficulty rating
With a previous software that I've used, each exercise was rated on a difficulty level from 1-10, and when searching for exercises, you were able to sort based on difficulty level, which makes it much easier when trying to find exercises for extreme beginners, or extreme experts if necessary.

I want clients to be able to add their own RPE for each exercise rather than just the whole session
For example first exercises squats could be 9/10 but last exercise leg curl could be 4/10 clients often rate the whole sessions easier then which doesn’t give me a good idea on what to progress

Yes, and it would also be useful if the client can see what rating that particular exercise has as well. If they look at the detail page or if there could be a small icon on the tracking page that can tell them quickly what the generally accepted rating of difficulty is for that movement.
