I have two events and some of the teachers are the same on both events.

How the "Cross-Event Sync" Works 
 When a teacher is assigned to multiple events, the system treats their time as a single shared resource: 
 
 
 Automatic Blocking: If a parent books a 10:00 AM slot for Teacher Smith in "Event A," the 10:00 AM slot for Teacher Smith in "Event B" is instantly blocked out. 
 
 
 Manual Blocking: If you use the Block feature (the "B" button or manual block) to close a time slot in one event, it will also show as blocked in all other events for that teacher. 
 
 
 
 How to Close Time on Only One Event 
 If you need a teacher to be available for "Event A" at a certain time, but unavailable for "Event B" at that same time, you cannot use the "Block" feature. Instead, you must Delete the specific slot: 
 
 
 Navigate to the Appointments tab for the event where the teacher should be unavailable. 
 
 
 Locate the specific time slot. 
 
 
 Instead of blocking it, Delete the slot entirely. 
 
 
 The Result: The slot is gone from "Event B," but because it wasn't "blocked," the corresponding slot in "Event A" remains open and bookable for parents.
