More granular access control

Dealers are tasking receptionists and others to do jobs that require them to have manager access to the platform, but this gives them access to other areas, like the employee tab, where they can see sensitive information. Dealers also are working with marketing departments that may need access to provision phone numbers or ad sources, but they don't want them to be able to make any other changes or see other pages. Dealers are working with training agencies (like Phone Ninja's or Blueprint) where they would only need to have access to the details tab.
