Feature Request: Ability to unstack multi-part movies

Plex Media Server Desktops & Laptops

This is a multi-part answer to the multi-part problem:

  1. Name the files to be in compliance with Plex Guidelines and a lot of these problems go away:
    The Hunger Games Mockingjay - Part 1 (2014).mkv
    The Hunger Games Mockingjay - Part 2 (2015).mkv
    These are two separate Movies - not one Movie in Two Parts (technically). Correctly named (above) they will show up as such. If put in the library horribly named, then renamed, use the correct names (above) and perform The Plex Dance as suggested by @astrofisher .

  2. If Plex thinks these two Movies are the same - they are horribly named. Fix Names (see #1)

  3. If for some strange reason you want these Movies to be conjoined-twins in some Freaky Frankenstein Lab Experiment join them manually:

  4. If for another strange reason you don’t believe us when we tell you Plex doesn’t do well dealing with Stacked Movies and you want to give it a go - to see for yourself how poorly, poor can be - follow the instructions:

  5. If you can’t be bothered renaming, Plex Dancing, following instructions, etc, and have two separate movies Plex thinks should be conjoined twins you can split them apart:

Note: My ‘Spaceballs’ are joined intentionally - not by some accidental joining or by the position of Orion in the night sky (one of them has a commentary track - the other one doesn’t - I pick the one I want at playback time).
Spaceballs (1987) [480p Commentary].xxx <— this one is in a folder (same name) with the Extras - placed first.
Spaceballs (1987) [1080p].xxx <— then this one is added outside the folder in the same library.
(the placement sequence IS important)

I have two versions of ‘The Big Sleep (1946)’ - Theatrical Version/Pre-Release Version:
The Big Sleep (1946) [Theatrical].xxx <— all in [Brackets] is ignored by Plex
The Big Sleep (1946) [Pre-Release].xxx <— so Plex thinks they are the same Movie - and ‘technically’ they are.
Plex dutifully conjoins them in a Freaky Frankenstein Lab Experiment, but I cleave them apart with the Split Feature - then make a notation in their descriptions which is which. I want these two movies of the same name separated.
