Is there a way to save an SDLXLIFF file that was created in Studio 2015 into 2014 version.

I have completed a translation in Studio 2015 but my customer requires his SDLXLIFF files in Studion 2014. Is there a way to save it retroactively in 2014? Also, is there a setting somewhere in Studio where I could request that all XLIFF files be systematically saved in 2014?
