Add user privilege to modify review templates but not other "admin" level items

We have many groups that use the tool and each would like to be able to modify thier own templates that suite their own needs. Our "admin" does not like giving people keys to the entire kindom. So I suggest adding a priveledge level for a user to be able to modifiy review template related parameters. I do not know the tool that well so if some parameters are "global" then maybe have those parameters be set on a group basis. So each group can override the global settings if they choose. This would give each group the power to customize the tool without affecting other groups...
