Create a limited administration role that can run reports on specific users

Right now the "reporting only" role can run reports on everyone. 

This is a problem because it prevents limited control in a large environment. If I want our account manager to be able to run productivity reports on his users that he manage, he will be able to run reports on VP's as well. Same with the warehouse manager, and the HR, and purchasing etc.... There should be the ability to control / filter reports allowed to be run based upon sub classes of the "report only" role.
