How to block time across all availability schedules for an instructor

Can I block an instructor's schedules in bulk?

The Appointments feature allows you to create multiple availability schedules for each instructor.

From time to time, you may need to mark yourself or other instructors as unavailable across all schedules (for holidays, sick days, or for general unavailability).

This can be done via the Block Time functionality on each instructor's availability schedule page. For more details on how to use it, head to How to manage an instructor's availability schedule/s
