I am not sure if this is what you are going for, but… I name the files as:

“Star Wars Episode x - title (year) [preservation name & version].mkv”

and put them in my Plex movie folder. Then, update the Plex library and it will show multiple versions available (assuming you have multiple versions of an episode). Use the option to split it into individual parts. Use Info to determine which of the entries is a particular preservation. Manually scrape or edit the metadata, as necessary.

In my case I just customize the titles, names, poster and background art.
