Different administrator accounts, one superuser

I use the CS-Cart in a web developer role. My client/colleague is in charge of the products we offer online. I want him not to access certain parts of the admin tool. His only concern is updating the products with the right price and stock information.

I would like to have two administrator roles. One “superuser” which can access all tools (that would be me) and another admin account which can only access product management.

CS-Cart 1.3.3 has the ability to set privileges for user account (such as: view/update orders, products, etc…).
