How To ...create crossover's?

[LeadMagnet]

OK....

I'm fairly new to Jellyfin and I'm having a display delema.

So to put some context on this, lets take a look at "crossover" episodes. I've not come across this mechanism of creating content, and wish whomever did would bite off their own head, but...

The Flash  (S05E09) - Elseworlds (I) ( "The Flash" Elseworlds, Part 1 (TV Episode 201 - IMDb )
Arrow (S07E09) - Elseworlds (II) ( "Arrow" Elseworlds, Part 2 (TV Episode 201 - IMDb )
Supergirl (S04E09) - Elseworlds (III) ( "Supergirl" Elseworlds, Part 3 (TV Episode 201 - IMDb )

So these 3 episodes form the "crossover".

My idea is to display it just like any other series. Just with one season, 3 episodes.

Now I can....

• manually replicate the files
  
• move them into a new folder called "Elseworlds"
  
• rename each file (E1, E2, E3) to remove detail
  
• remove meta info from each file (ExifTool is your friend)
  
• then spend time manually creating/editing the detail
  

....but all of the sounds like a bunch of work 

Is there an easier way of telling Jellyfin "..look...grab that one, that one and that one and display it as this..."???
