Question about Integration with WP All Import

So, I have a (possibly stupid) question that I wasn’t able to figure out on my own. Do you have any settings/further plugins for integrating with WP All Import? When uploading files of thousands of items I’d like to be able to select what language the upload is for as well as what items they are the translations of. I asked the WP All Import people, and they don’t have anything on their end that can do that with Polylang, so I’m hoping that you guys might have something in the works.
