Security Realms, upgrad right in group!

Question about my Realm, in the Group operators and Group Adminstrator settings.
I am trying to make my group Operator to access some particular pages of my admin
console where only group administrator can execute some action.
Upgrade the group operator rights in a particular page of my admin consol.

I know that:
Operators: can view and modify all resource attributes and perform server lifecycle operations.
Administrators: can view and modify all resource attributes and start and stop servers.

Exemple: I want to give to my group operator the possibility to stop and start the servers
and in the same time i don`t want to add the group administrator to the operateur group.
