PLEX has a feature called COLLECTIONS. When you add the folder there is a pulldown to decide how you want collections to appear. I personally chose “Hide Items which are in collections” Add each version and have Directors Cut, Extended Edition, 3D, Remastered etc. for each title. You can edit the cover art individually. Now choose EDIT and select the TAGS tab. At the Bottom in Collections add the movie title. Do this for Each Individual Version. Now if you chose to Hide items which are in collections the movie Title will only show up once. When you select this Title, the different versions will show up Inside this container.
I have 3 different files for The Martian. The 3D copy, 1080P & 4K. The 1080P & 4K are together under 1 title where you can chose Play Version.
1 Movie can be in multiple Collections.
I do this for Trilogies or to Catalog all the Marvel Movies.
Just make sure to lock the title and Catalog to ensure the seperate titles dont merge as 1 title again.
