Support for Extra Content: Behind the Scenes, Extended Versions, Featurettes, Documentaries, ect ect.

[ThisIsStupidGitHub]

Is your feature request related to a problem? Please describe.
My first attempt using this program, I found it doesn't distinguish between the 'Theatrical Version' of the movie, and the 'Extended Version'. Nor any of the bonus content such as featurettes, behind the scenes, ect ect. It just named them as "Movie-part-1, Movie-part-2" ect. which will really screw up how Jellyfin sees it as it will read it as multiple parts of a single movie.

Describe the solution you'd like
Not sure if this is even possible, but I used "Rename My TV Series 2" to try to get the naming of my TV series files in the correct format. It was able to pull up the different releases of DVD/Blu-ray, allowing me to select the correct version, pull up a list of what should be on that set, and reorganize the files to match what is in the expected list, then batch rename them to match in the proper file structure that Jellyfin can read (it wasn't perfect mind you as it gets tripped up from multiple episodes parts named the same thing). If possible, it would be very helpful if this could do something similar (TMDB seems to have 'Alternate Titles' that are the different physical releases. At least for the one movie I did check.

Describe alternatives you've considered
I'm still hunting for this solution, but thus far, the only thing that works is manually renaming the extra files.. which.. kind of defeats the entire purpose I tried this program for.

Additional context
The only movie ive tried so far, where I ran into this issue is Stargate. Which i have the 'Stargate: 15th Anniversary Extended Remastered Edition' version of.
