Double episodes (Metadata)

Hey! Just got the new Apple TV and I’m very happy with Infuse so far!

One thing (maybe two):
How should I name double episodes? Kodi accepted them as “Lost - 6x17 - The End (1) & 6x18 The End (2).mkv”, but it does not work with Infuse.
The same with movies containing two parts: Like “The Lord of the Rings The Fellowship of the Ring (2001).CD1.mkv” and “The Lord of the Rings The Fellowship of the Ring (2001).CD2.mkv”. It won’t recognize them correctly.

Best wishes!
Uwe
