Setting The Language to English or other in the Metadata on Export from FCPX

Hi There,

I am trying to set the Language in the Metadata of the file when exporting out of FCPX but I can only get undefined as a language...Is there a way to set the language as there isn't an option that I can find in FCPX...OR is there a way of setting the language once exported without creating a whole new file?
