Maintenance of Simulation Sets

On ASCP due to the fast changing parameters on safety stock and several other attributes, the business decided to use a simulation set to 'maintain' the information.  Is there a way to allow a responsibility to update the values in a simulation set such as safety stock but not create or delete the set? My first reaction was no and that we would have to remove the access from the menu and maintain that information via a program that IT would run.  Any ideas?
