Modifying a 3rd party affiliate script

I need to have a 3rd party affiliate script to be customized to my needs. ## Deliverables Currently the Administration section allows setup other "Super users" or "not Super users". The only difference between them is that "not super users" cannot delete the super users - but I want this to change to following: Super Users will assign admins based on check marks they place on each environment/menu-item in the script. If a menu item is checked, then when that admin logs in, we will show those menu item only. Please have a look at the images attached.
