You are able to make copies of your different Library events so that you can easily duplicate existing events and customize them as needed!
To copy any event in your Library you will just want to follow these simple steps!
1. Go into your Library
2. Find the Event you'd like to Copy/Duplicate
Once you have clicked on the event, at the top of the event, there will be a "..." button to the left of the Share button.
3. Click Copy
When you click on the Copy option it will automatically make a copy of the event and pull up the new duplicated event. You should then be able to see the duplicated event with "Copy" in the title.
From that point you will be able to make any needed edits or additions to that event and then save the changes you will be able to click the Done button.
