If you have a special event that you'd like to track separately from normal Sunday's such as Christmas, then you may want to use this Copy Locations From Another Event feature! This will allow you to create a new event, but keep all of your locations, filters, options, and label settings from another finely tuned event.
You'll see the option when creating a new Event
When you're creating a new Event you'll see this page on the Labels & Locations tab. If you have another event in your account the copy locations feature should appear on the bottom. This will copy all of the location names, filters, labels, and option settings that have been made.
