Ideally, guidelines for changing Sub rules in Italy, would be much appreciated.
I've taken the following steps, thus far:
Rules > Add Nation Rules > Italy > Add Lower Divisions And Cups To Existing Structure > Convert to Advanced Rules > Serie A > Substitution Rules for Division Level.
What should I do from this point onwards? I'm not sure where to go with this; however, I do see the dropdown to select the desired rule, from this point.
Your help would be much appreciated. I can provide images, if necessary.
