Changing default email on Template site.

Hi,

I am building a multisite network of stores. I have Marketpress multi-network activated and I have created a template blog that is used when a new user is registering a new blog/shop.

At the moment, the Store Admin Email in Marketpress for any new blog is the one that is defined in the template blog, which is the Main Admin email. It is very important that the Sub Store Admin Email in any new blog/store would automatically insert.

Is there a way that the sub store/blogs email be included in the store/blog email rather than the Main Admin email? If I put the main admin Email on the template site, it would automatically be the default email for the new blogs/sites.

How can this be achieved?
