[Xymon] hobbit-alerts.cfg - Can HOST be within PAGE?

In the hobbit-alerts.cfg file can a HOST line be withing a PAGE line to select particular hosts based on what page they are on? For example, if we want to mail alerts for all the servers on the SERVERS page that begin with the letters d or t and only the ones that are on the SERVERS page would the following entries work?

PAGE=SERVERS HOST=%[dt].*\.ourdomain\.com MAIL $ADMINS SERVICE=disk,cpu,memory,procs DURATION>1h COLOR=red RECOVERED REPEAT=8h FORMAT=PLAIN TIME=W:700:1900
