Editing question for FM 2018

Hi

Apologies if this is the wrong place. I could not find an FM18 Editing room

I have tried to create a 2 tier league system for Australia but it does not work in the game.

I did so in a previous version (FM15 I think) by putting Australian teams in the Malaysian league and the changing the nation info of the malaysian league to Australia, however this does not seem to work now. Any ideas on why and/or ideas on how to make a 2 tier system for Australia.

Thanks a lot
