Bulk Edit Lists

This is related to copying lists but slightly different.  I was thinking of ranking my favorite titles NOT related to what I rated them.  I often try to rate on the overall content or production. But sometimes even if something is trash it can hold a place in my heart ❤️ 

I wanted to simply copy my Completed list to a custom list.  If there was a bulk edit it could also be done by selecting the titles I want from a list then doing an action to copy those titles to another list.
