It would be helpful if we could set a number of appointment slots available and once all those slots are booked then it no longer able to be scheduled. Similar to how there is a booking setting for Daily Session Limit - except it would just be Service Session Limit. We administer limited seasonal flu + covid vaccines, it would be so great to enter that we have 10 doses of covid vaccines, people can book whatever time slots work for them but once 10 slots have been booked then no more appointments can be scheduled. Currently I have to manually watch our inventory and compare to the appointment list on a daily basis.
