Copy Template Settings on All Multisites

I would like to have the network sites to have the same theme settings without having to reconfigure the template settings for each individual site. Note: I am not allowing anyone except for admin to create sites. And we are creating the sites based on state. For example: california.mydomain.com and iowa.mydomain.com. So for the US I will have 50 sites and I don't want to have to set up the same settings 50 times.
