Get subtitles based on language

I have a little problem with Mezzmo. When you have multiple subtitles for the same file, Mezzmo will not get it because he can't find any subtitle file with the same name.
For example, a lot of people have subtitles like this:

my_movie.mkv
my_movie.eng.srt
my_movie.por.srt

Would be great if I could select in Mezzmo the default subtitle language. If English is selected, it will first try to get a SRT with the same filename of the video file, if not found, try to get my_movie.eng.srt.

Also, is it possible for Mezzmo to get the internal subtitle and stream it separated? Many TV's can handle external subtitles, but not if it's embedded with the video (mkv's for instance). That would avoid the transcode process just to burn in the subtitle.

This will be possible with the next major Mezzmo update that will include our subtitle engine.
