Current Issue:
Right now, the only way Trainers/Owners can schedule future appointments in the system is if the client has credits available. This creates two operational problems:
1. I either have to manually schedule the next 4 sessions every time a client pays for credits, or;
2. I have to add credits to their account in advance, which can cause confusion about how many sessions they actually have left.

Proposed Solution:
Allow trainers/owners to schedule future sessions even if client has limited or no credits available, but have the system automatically notify the trainer/owner when an upcoming session(s) has not yet been paid for.

Reason for Request:
This would allow trainers/owners to see their future calendar in full, making it easier to manage availability for other clients who might need to reschedule due to vacations, or events, or other conflicts. It prevents booking overlaps, improves scheduling flexibility, and streamlines workflow.

If there's already an effective way to manage this within the current system, I'm all ears!
