Polylang bulk set language for content

Hi,

Something went wrong with updating to the newest version of Polylang which forced me to uninstall Polylang and re-install it. This meant that all my media and pages weren’t categorized by language anymore.

Now I don’t have a lot of pages, so I did them manually. But my media, I rather not. Is there a way to bulk set language for content? All my media that needs to have the English language contain a unique word (“days”, “weeks”, “months” or “years”) so even If you have a SQL query by any chance that would be a real lifesaver. (I am aware of the dangers of such query and know how to make a backup beforehand)
