Ability to set default song order in a public playlist to recently added

[COLELSTILL]

Currently when people look at my public playlists or when I share a playlist, the order is based on oldest to newest, or whatever order when you created the playlist. 

Need the ability to change the default sorting order (especially to most recently added), so that way when people look at my public playlists or when I look at other peoples, I can see what they've most recently added!

P.S, I am aware you can add all the songs to a new playlist in that order, but that means every time you add a song you have to recreate the playlist to avoid it going to the bottom (waste of time).
