I have set up a role called customer admin. This is a role for the client who wants access to back end with the ability to set up their own users (customers) on the web site. When we assign the user to this customer admin role, we would assign the customer group to that user and then the only thing we would want them to have access to would be the orders and customers associated to that customer group. In addition, when they set up a new customer, that customer would automatically be associated to that customer group. Is there an extension out there that will do that?
