[Feature Request] Subtitles with language codes topic

I couldn't find this request on the forums so I'm posting it myself. I would like to see the ability for MX player to detect subtitles based on the language code. Both 3 letter and 2 letter codes would be ideal. E.g. movie.nl.srt or movie.dut.srt (both dutch).

Right now I have multiple subtitles and when I play a video it loads (what seems to be) a random one, but only one and ignores the rest.
