Multilanguage files and library division

[Frankz]

Hi all!
I'm new to Jellyfin.
I share my library with my family, I watch videos in English, they do it in Italian.
I've created 4 separate library:

• movies ITA
  
• movies ENG
  
• series ITA
  
• series ENG
  

And when I manually add files in {Thing we don't talk about - TDP}, I assign each to a category that automatically moves the files to the appropriate folder.
Now using {Thing we don't talk about - TDP} and {Thing we don't talk about - TDP}, they automatically moves the files into TV and MOVIE; if I select a series that it's in Italian I manually edit the path in {Thing we don't talk about - TDP} (and the same for movies), but what should I do when I select a series/movie that is multi language?
Is my library division correct or should I use a different one?
I would use just movies an series, but in the filters I can't see language, so we don't know which one is in which language.

THANKS!
