Need for more control to build custom lists

[Brent Seizer]

I am trying to create custom system list to keep my servers seperate from my printers.
I want to create nested condtions.

The problem I run into is that I create rules such as
SYSTEM NAME BEGINS WITH CA40

This is fine for servers once they are configured properly. I want to identify the servers that have yet to be configured completely. What I want is something that says

IP ADDRESS BEGINS WITH 10.1
AND
SYSTEM TYPE = SERVER
OR SYSTEM TYPE = CLUSTER

This would identify servers that have not been fully configured, that may not yet be added to DNS.

The summary of my query is that I need more control over AND, OR.
Is there a supplemental update to the CMS program that allows for more sophisticated rules?
