[Plugin: League Manager] Categories and Management of Leagues

Hi, i’m trying to create a site of futsal, and i need to show all the leagues of different places, but with the actual League Manager it’s a chaos.

For example:

I need to show the leagues of… Europe, including each country, with his different leagues. Maybe each country has 10 leagues.

I need to organize it with categories, or something similar, and it use later a function in a page or post to show “all the leagues” of germany, and all the leagues in other page/post of england, spain, italy, etc…

How can i create it?
