How can I change the number of times the run/walk interval repeats on my Vivoactive 4? I see how to change the times but not the number of repeats. It seems stuck on 4 repeats and I'd like to do more. There does not seem to be in the instruction manual and all the internet help I've found is for creating new workouts. I like the run/walk built-in but want to change the repeats. Any help?
