Show missing movies from a collection

I hope this is the right place for this…

Just an idea, but I think it would be great to show something (like a grayed out poster) if you are missing movies that are part of a collection. For example, take the movie Prometheus for example. Since plex is already scraping collection info from TMDB (https://www.themoviedb.org/collection/135416-prometheus-collection?language=en-US), and I only have 1 movie (missing Alien: Covenant), I think it would be great to somehow indicate that I am missing it.![]
