As far as the artworks are concerned, I am not sure if I understand what you mean. Since Movie Versions are not created automatically as it happens for Movie Sets (when the relevant setting is activated), all movies have their own artwork lists. But when they become part of a movie with Movie Versions... that info is lost and you are only left with local artwork loading as an option. I don't see why you thought using the same artwork for all items would be involved, since pretty much all movies have multiple fanarts/posters/etc. available. But they are simply not accesible through Movie Versions. At least, that's what I'm experiencing.

You can change the artwork from the information dialog.
