In order to enable weekly booking, you need to create a price plan for Season booking.
You can find a general introduction to the creation of price plans HERE.
If you want to let your coaches/assistants/ members book a time slot for a whole season, you need to enable Seasonal booking while creating the price plan.
TIP: If you chose this option so that coaches can book the field for training, you could choose only to allow coaches (maybe even only from a specific team) to book the time slot.
You can also have two price plans for one resource. For example, the Football field is reserved for training in the evenings, but during the day, members can book it. It might be helpful to have a seasonal booking for the training, but not during the day, when members can book the field. Then you create two price plans, one with seasonal bookings for the coaches and one with single bookings for regular members. When you choose the time slots (under Seasons, more information HERE), choose the according price plan.
Under Booking in the subcategory Seasons you chose the price plan you want to use for the time slot. For the football field, two price plans have been created. If you want to enable weekly booking, you choose the according price plan under Seasonal Booking.
The season template might look like this:
