Searching tracks through our playlists

I have created many playlists and sometimes I  don’t remember if I have already put a track in one of them. 

It could be great if in this menu (the user playlist menu)

we could have a “search container” where we can type the name of a song, an album, an artist and then we can see which playlist(s) contains this song, or album, or artist.

Thx a lot for your time.
