Automatically add playlist songs to liked

With the new plus symbol replacing the heart on spotify, it’s hard to tell what songs i have liked. also, whenever i have spotify playing in the background it’s hard to constantly like songs. mainly i listen to one of the automatically updated playlists, and eventually the songs fade out of the playlist before i got a chance to add it to my liked, and the song is lost forever. it would be very useful to be able to enable an option that adds a song to liked automatically if it appears in one of these playlists.
