I'm slightly confused on naming a double tv episode.
Example... I have Gotham season 3... double episode with the last 2 episodes 21 and 22.
So I know to make it

S03E21E22 - name of episode.mkv

But what should I actually use for the name of the episode since these are listed as 2 separate episodes on thetvdb?... with completely different names... as in not a part 1 and part 2.
Or do I leave the name blank and let MC3 handle it?

EDIT>>>I'm even more confused... I just checked my Seinfeld collection where I knew there were some double episodes.
Season 9... the last 4 episodes.
These are my files

S09E21-S09E22 - The Clip Show (a.k.a. The Chronicle).mpg
S09E23-S09E24 - The Finale.mpg

When I look at these in Kodi they are listed as four separate episodes.
21 and 22 are both the same file when played and 23 and 24 are the same as well.

Can someone tell me what I'm doing wrong here?
