Option to Edit Playlist Poster

I’ve recently decided that Playlists is the best way for me to organize things like “Marvel Cinematic Universe” movies and “Disney Animated”, etc. based on my set up. It would be a nice (small) feature if we could edit the thumbnail that appears on the playlist homepage with a picture that represents what’s in the playlist. For example, I would use the MCU logo and the Disney Castle logo for the two aforementioned playlists.

Early 2021 clean-up: duplicate

The requested feature can already be achieved using collection!
