Currently in the POS permission groups there is a single control granting "manager permissions" which is a broad permission set ranging from the ability to adjust tender declarations to the ability to deactivate POS devices. There should be a more granular control set that allows system administrators to select what functions managers have the ability to do within a store environment.
