how to see on which playlist a selected song is?

When I select a song from Library > Songs I am wondering how I can find out on which Playlist that song is?

I don’t think that function exists in iRp. You can search within a playlist.
I can see how some users might like to search the playlist-list for a tune.
I know if you try to add a song to a playlist that already includes that song, the app won’t allow it (unless you make a duplicate).
