If you have an event that uses similar rooms, you can duplicate it to create an event that requests the same rooms and resources.
From the event's Overview tab, select Duplicate.
Fill out the information the same way you'd create a new event. When you click Submit, you'll go to the new event, and the schedule, rooms, and resources from the original event will be duplicated into the new one.
When you Save, the requests will be sent to approval groups.
