[Feature Request] Add language to the exported XLIFF file name

Hi, I have a problem with exporting exliff files. The filenames do not have any languge added to title only numbers. Exs -sv, -no and so on. How do I change this. We are using external translators. Filename example: Prosero AB-translation-job-18 should be Prosero AB-translation-job-18-da. Can you tell me how to change this?
