About to embark on some cross border leagues and I want to setup a rule that limits the number of 'foreign' players from outside the countries involved but as the leagues will have to be based in a country need to assign the other countries as not counted as foreign? Had a quick look around basic and advanced rules but couldn't find anything.
e.g. Scandinavian league - based in sweden but allows unlimited danes, norweigans, finns but limits all other nations.
