Let customers choose a schedule themselves in the app

It would be helpful if customers could choose a training or nutrition plan themselves when no plan has been assigned to them yet.

How it works:
Clients receive an overview of available plans, for example based on goals, experience, or dietary preference.
They can select a schedule themselves and start immediately.
Coaches can set which schedules are available and optionally make suggestions.
This ensures that clients do not have to wait for an assignment and can get started immediately, while coaches retain the flexibility to make adjustments if necessary.
