Seeking Solution for Nextcloud Tables Data Input

I like where this app is heading in terms of managing some reporting data. I have a scenario where I have regional people around the world that I need to have report on statistics in different countries. The stats are the same types in all locations. But I want to build views off the table that limit selections in the drop down to define which country the report is from (sure they could type the name in but we all know people do not type accurately every time).

So I see having a master table with a Country field listing all of the countries, then having a view for the person overseeing Europe to only see European countries in his selection options.

Am I missing an easier way to pull this off now? Or do I need to wait for some conditional filtering to become available?
