With the new feature of setting your attendance status, we can imagine that you wish to have your attendance status on a default value for certain events. Fortunately, you can do just that in each of your calendars. (see image below)
From now on, you will automatically attend soccer practice every Thursday afternoon. Strained your ankle? No worries. Just change your default attendance state to un-attending and you will have some time to recover. You can also set your default attendance state to only attend the events you created yourself.
