Inserting a playlist in a playlist (workarounds)

While AppCenter does not support a true “nested” playlist, you can retain some of the functionality of inserting a playlist in a playlist in the following ways.

Save the list as a program, then insert it into another playlist as an event.
Use multi-item select and copy/paste.
Copy/paste events or sections within the same list or from other lists.
Copy the list in the Clips pane, then load and edit the list.
