Protection of knowledge and data

As a professional coach, you have your own working method and strategy. When professional athletes come to you for advice and guidance, you obviously want to help them with that. However, you do not want your knowledge and data to be simply transferred to other coaches and teams when the collaboration ends. So there should be an option to delete all planned workouts/assignments without deleting the athlete's uploads for professional coaches.
Now we have to manually delete this every time.
