Filter videos by creators set country?

Hello, I use language reactor to study Portuguese and was wondering about the possibility of being able to sort videos by whether a YouTuber is based in a specific country?

here is an example I made.

this information could be found in a YouTubers about section and could help filter through videos that aren’t in the language you’re looking to watch.

this seems really helpful but it may have to rely on IP addresses or if the youtube set the language in their vid

Bit tricky, will think about it.
