I do my "Admin-Surfing" with the help of an extra Profile.
First add your needed IP´s as Hosts or Network under "Definitions / Networks". Then (in Proxies / HTTP) simply add a Profile with the SP Settings you need and add an Assignment with that Profile. Under "Assigned Network Blocks" you can then add the Hosts or Networks you need. The last thing is the sequence of the Assignments. The new one should be first.
