How to blackout dates across multiple event types

If you have multiple event types set up in your appointment availability, it can be cumbersome to manage the blackout dates by going through each individual appointment:

However, there is an easy way to apply blackout dates to all of your available event types.

To blackout dates across all event types, create a calendar event for the dates you are unavailable and mark that time as busy. 

For example, if you're on vacation from 7/1 - 7/10, you would create the calendar event as shown below. 

Marking the scheduling status as "Busy" will remove those dates from your list of available dates within the scheduling module.
