Add Option to Duplicate or Save New List (when you're in an existing list) in List Builder
Add an Option to Duplicate a List or a Save New List Option when you're in an existing list. If I want to create two lists that are similar, I have to create a brand new list every time. It would be great to edit an existing list, make changes, and save as a new list. Similar to what you can do with updating a favorite report and saving it as new or updating an existing.
