alert rules and PAGE

What is the name of the top page. I have some primary servers on the tape page and then several other pages with rule for the page like this:

PAGE=WINNT EXSERVICE=trends COLOR=!purple MAIL $PG-NT REPEAT=30 DURATION>2 EXSERVICES=cpu,msgs,memory RECOVERED MAIL $PG-NT REPEAT=30 DURATION>10 SERVICES=cpu,msgs,memory $ESCALATE

but this particular rule also gets all alerts for the top level PAGE. If there is an internal name for the top PAGE I could use the EXPAGE to prevent this.

Also any chance of adding a group level rule? thanks
