Vendor Administration user group, How to set vendor's other users to user group.

During opetating CS-Cart we are facing some issues.
I have a employee to process all received orders, but when he logged in, he can see dashboard and all amount and sell, It can distract the employee.

My questiong is how to set permission access to vendor’s administration and his employees/users.

  1. When my employee login, he can redirect to order page only, he should not see the dashboard(Analytical and amount of sells).
  2. When we assigned a employees to adding the products he can not access orders and other section.

This is just example, The problem is how to give permission access to my employees as vendor.
