How do I enable two cars per team in my league?

I can't find the button.. It's possible for 16 teams or less, right?
Season is finished. 

Thanks in advance.

I don't think you can change it once the league has started. You'd have to make another league. Unless one of the dev's can change it for you?

Please do not PM Jack or Andrew. Please log a call with the helpdesk & Aaron will be happy to assist.

Just to put the definitive answer out on the forum, if you start a league as a 1 car league, it cannot be changed to a 2 car league afterwards. It is not something that can be changed by the development team. You will need to create a new 2 car league and the mangers will have to switch over on their own.

Thank you for that Aaron
