Is there any way to change the AI difficulty during a custom championship? It's a bit frustrating to run the first race meeting and feel that it needs to be raised or dropped by one or two percent but there seems to be no way to do this, other than start the championship all over again. If it's not possible, then I'd really like to ask the devs to consider adding this. It makes it much more flexible in matching the difficulty level as I go along and helps allow for any variations in the circuit difficulty too.
