Hi!
Instead of Sanket's reply, you can do next:
1. Set the Administrators group as hidden.
2. Create another group named Administrators.
3. Create another group named Assistant Administrators.
4. Add all the users that you want as admin in real, hidden administrators group.
5. Then add assistant administrators to Assistant Administrators group, and the rest of administrators on Administrators group.
