Your availability can be repeated as needed and set individually. Click on an existing availability or create a new one and click on Create recurrence. Now you can define the repetition (daily, weekly, monthly, yearly), the interval repetition of […] week(s), the start, the applicable weekdays and the end for the repetition of the availability. You can decide whether you want the repetition to never end, to end after […] times or on a specific day. Finally you will find a summary of your selection, which you save with Update.
When this is done, update the availability again and it will be automatically applied and stored in the system.
