Email Notifications - Admin should have ability to toggle on or off by team or individual

Our teams function separately and we don't want team members to receive summary or activity emails.
I don't like the precedent it sets for monitoring/comparing hours and changes to files, outside of the Administrative or Managerial capacity.  It allows people to ask questions and "check up on" coworkers in a way that we don't like.  Why can't I turn of those email summaries and notifications depending upon user role?  No one needs to be getting them - if anyone there should be the option for Admin Only.  Currently this can only be adjusted on individual accounts and it has already created an issue in the first week.
