Sync Public holidays and Closed days throughout Calandars

It would be great to have an option to select relevant appointment books when inputing unavailable blocks for public holidays or days closed etc so these days are reflected across all relevant cliniko appointment books . This it would save so much of my time.

We consult at multiple locations and therefor have multiple ‘appointment books’ however when we input public holidays or days the doctor is away ect it means I must block out these dates in each appointment book individually.
