When you create a new event, you can copy an entire team (including all member restrictions) from a previous event instead of setting up each member again.
Copy a Team from a Previous Event
Open your new event and click the blue Team button on the event page.
Select Copy team from previous event in the upper-right corner.
Choose the source event from the dropdown menu.
Click Copy Team to confirm.
Select OK in the confirmation pop-up.
All team members and their assigned restrictions are automatically added to the new event.
