Assign specific names to additional parts of movie

[ragnarok]

Holy cow! I had no idea about this Movie Extras feature. Thanks a lot for pointing it out! It works like a charm for many video albums like Coldplay's "Live 2012", in which what I was calling Part 1 was actually the main concert video, while Parts 2 and 3 were indeed extra featurettes.

I, however, still have a related issue for some other video albums like "Völkerball (2006)" by Rammstein. This contains four main titles (not one main title with other smaller featurettes), which are live performances in Nîmes, Tokyo, London, and Moscow, ripped as separate video files. I have now named the files as:
- Rammstein - Völkerball (2006) - Part 1.mkv
- Rammstein - Völkerball (2006) - Part 2.mkv
- Rammstein - Völkerball (2006) - Part 3.mkv
- Rammstein - Völkerball (2006) - Part 4.mkv

By doing so, Part 1 appears as the main video, while Parts 2, 3, and 4 appear under Additional Parts. This, however, is not ideal. I would like to identify each video by the city name (Nîmes, Tokyo, London, or Moscow) rather than a vague part number. Is it possible to have either:
- The city names appear under each video in the Jellyfin interface; or
- The city names appear in the file names, while Jellyfin still identifies them as multiple parts of the same movie?
