turning challenge mode game to non challenge mode
 

So I started a game in challenge mode with the expansion Mariners in 1977. For some reason, my owner expects me to reach the world series this year so I'm probably going to get fired as we're 25 games under 500 or something in August.

I don't want to get fired, I want to stick with the team and see if I can turn it into a winner. I can't find the option to not get fired anywhere.

Can I do this or am I screwed because I started it in challenge mode?
