How to blackout days/months when using repeating availibility

We are using repeating availability with set days/times. We need to blackout the entire month of August for vacation as well as the occasional day during the rest of the year. Please let me know how we can do this using google calendar, thank you.

@Michael you can add busy events to your Google calendar, that will block the time on YCBM: How to block time in your schedule - YouCanBookMe Support

If you are setting up Group Bookings (more than one person can book) add YCBM-OVERRIDE-UNITS to the title of the event you are adding to the calendar.
