It would be great if we could customize workouts on specific days week after week like on the mobile app. And, it would be even better if we could schedule progressions with different exercises for a program. For instance, I may keep a client with dumbbell squats for 4 weeks, but I may change out the exercises that I superset it with. I keep "staples" in certain programs and adjust other exercises as I see fit. Super beneficial to have this feature for programming when things constantly change in a clients life.
