Eurocups squad rules

Hi, today i started editing my fm.

Idea is to change limits more strict, so italians play mostly at italy, spanish players at Spain etc.

I have already changed the countries i use, rules to this

Also i want to change the Euro cups. So the limits are the same as at the countries (this pic up here).

But i don´t know how... Somewhere i read that "champions cup" must be placed at nation (like Hungary) and then it can be changed. I tried something, but no result.

Pls help. And sry for my bad English.

if you want to change euro comps rules-you need to recreate whole system. after that you will loose coefficients and probably have some more issues. read this
