Editing the Match Day Stadium??

Greetings Fellow Managers,

I'm trying to edit my match day stadium - i.e. the one you see in game through the 3D game engine.

Now, using FMRTE you can easily change the size of your current stadium through altering the capacity - easy and peasy.

However, lets say you have a stadium with four distinct stands but you want a bowl type stadium. This seems harder to do.

I've managed to point my team to a stadium from another team from an inactive league and that does work. That gives you a different looking ground etc. Although, this is a gamble as to what you'll get. It also suffers from the waiting to the following season and so on.

What I'd like to know is;

Has anyone else been tinkering with this?
Found a way of changing the stadium?
Found a way of choosing the look of your stadium?

Thanks in advance

Rich
