Adding Tracks to Playlists

When you right click on a track you can "add to playlist" for any of your pre saved playlists, but it only lets you add to one at a time.

It would be cool if the drop down menu was a list of boxes that you could tick/ select to allow you to save a track to multiple playlists at the same time so that you don't have to repeat the process for every playlist you want to save a track to
