Question for Content Manager & Custom Championship

Salute

I want to know how to create a custom championship via the content manager. Unfortunately there is no documentation about this. I usually create my championships ingame.

I found some pretty nice generic preview pics but they didn´t show up in content manager under the championship tab. The path should be correct with: user-documents-assetto corsa-champs ?

So,any help here is...
