Store Admin Email of Marketpress in new blogs created with template


I am building a multisite network of stores. I have Marketpress 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. It is very important that the Store Admin Email in any new blog would be the same as the admins email, the one that has registered the newblog.

How can this be achieved?
