Editor (Need help)

Hi.

I just have one question. I'm about to start a very big project, which include me transfering every player in the game back to their home country. This means, Bale plays in the Welsh league, Henrik Mkhiraryan goes back to Armenia etc. I also want to put in a international rule, that clubs can only buy players from its own country. So my question is, is there a very easy way to make this rule? Can't seem to find a quick solution.

Hope that any of you is an expert in the Editor.

Set the maximum foreigners allowed to zero on the squad rules.

Yeah, I know this is possible to do in every single league, but not an international rule. Or am I wrong?

No one?

No you would have to do it for each nation.
