Is anyone willing to help with some VBA code for this situation I am facing with daily?

I have many Word documents with several hundred pages of bilingual text(and multilingual sometimes) structured like below and I have to:
-hide one language(or more) every time maximum one or two paragraphs at once(vertically) , even smaller and smaller sentences at once, because not every file I get is nicely divided.
So it's a very tedious job, horrible.

The proofing is never correct(from the client) so I can't use find(language)&replace(with hidden)

Or, a solution for highlighting one language(column) would be also awesome as I can afterwards hide what is not highlighted?

Would be grateful!Thanks!
