Adding Audio tracks/subtitles to files in iTunes?

[One Love 1867]

Hey all, hopefully just a quick querie..

I've been adding some movies to my iTunes library, and have acquired different audio tracks (5.1 Surround, for example) and subtitle files for the movie. However, when I add the movie file itself to iTunes, I can't work out how to sync them up with the extra audio tracks and subtitles etc. I know you can use optional audio tracks in Plex, but is it possible in iTunes?

Thanks in advance for any help..

You need to use a tool like Subler to mux all of the tracks together.
