Metadata fetching/local metadata for movie collections?

So a lot of my movies are part of a series/trilogy/collection. Like for example I have one folder called “Star Wars - Complete Collection” and inside are the 6 movies. The six movies themselves fetch metadata fine but my collection folder is left blank. Is there any plan to add some sort of implementation for collection folders? Kind of like how it works for tv series folders. I know themoviedb.org database has folder art for movie collections.

Even if automatic metadata fetching wasn’t available, even manual metadata would be fine too and I could add it myself. The problem currently is that manual metadata only works for individual files, not folders. And in this case it wouldn’t be complete metadata as much as just a cover art picture. Thanks!
