Is there an ability to duplicate playlists?

I listen to a playlist that isn’t mine and I was wondering if there was an easy way to duplicate the playlist and make it my own ad a separate playlist.

Yes, you can, but you can only do it on the desktop as far as I know.
So you need to click on the first song in the playlist, then go to the end and hold down Ctrl + Shift and click on the last song. Then right-click and it gives you the option to add the selected songs to a playlist.
