How to bulk revert all translations made by a user?

I’m an admin for on a file-based project in Transifex where we had a translator replace all unreviewed translated strings in one language with their source strings. I’ve already looked through the documentation, but haven’t found a way how to revert such changes. As we’re talking about thousands of strings, going through them one by one isn’t feasible. What would be a way to revert all changes made by a specific user, so that the previous translation is used again?

Because this needs a bit more of an investigation, please contact us at support@transifex.com with specific strings , resources and project so that we may look into this a bit deeper.

Kind regards
