alerts

Is their functionality in hobbit to do alert escalation? I read through the man page and nothing jumps out as a method to do this. I ask because we have a small 4 man rotation of oncall personal and I'd like to setup all alerts to go the primary oncall contact and if no acknowledgement has been made in X amount of time, send out an alert to the group. That way everyone keeps their pagers on, but only the primary receives the first alert. Any assistance is appreciated.

Thanks
