Set Workouts to REPEAT (just as we can with tasks), instead of solely copy/paste.
This would mean these workouts would be CONNECTED, and if you change one you would have the option to:
  • "Change this workout only?" (which would remove the repeating series)
OR
  • "Change all workouts in series?"
This would save a massive amount of time when you need to update a workout, and have already scheduled it for multiple weeks.
