Editions are a Plex Pass feature only, so you’re stuck with using versions
https://support.plex.tv/articles/200381043-multi-version-movies/
I would name them like this and Plex dance them
Tron (1982) {imdb- tt0084827}.mkv
Tron Legacy (2010) {imdb- tt1104001}.mkv
Tron Legacy (2010) - 3D.mkv
The 2nd two movies will get collapsed into one poster but they’re both there
You have to select the movie then “play version” and select the one you want
Editions show up individually in the library so it’s nicer having them permanently separated but that’s not an option for you, unfortunately
