Multiple files in same movie directory

Is it possible to have 3-5 versions of the same movie files in different formats and the same with sound files and subtitles, and from that plex choose the one that fits the client Best to avoid transcoding. Example:

Blahblah 1080p h.264
Blahblah 720p h.264
Blahblah SD h.264
Blahblah 64khz.en.mp3
Blahblah en.srt
Etc etc

Kind regards,

Yes, you can have several versions of a movie.

No, Plex does not support external audio files.

No, subtitles files have to be named exactly like the video file they belong to. (plus of course their language code.)
