Backup playlist for deleted tracks

Hello!

New in the App here. Is there a way you guys can add some sort of backup playlist that is filled automatically from tracks swipe-removed from playlists?

Then also, consider for duplicates or add them anyway on this sort of backup playlist. Im scared to regret deleting some tracks while cleaning a playlist I have with more than 3.000 tracks.

Also, this will probably help me later to re-assign this deleted songs to an another better-fitting playlist.

Maybe this feature exists, sorry if it does.

Thanks and congrats with this amazing App I just discovered.
