Until it is enhanced, here is one possible option that will get you close to what you want:
Create a scheduled report to run every hour.
qry format = "matched incident ranking". make sure "use only firing events is checked". Click on the events column in the query and change "Restrict to Severity" to "RED". Change the time to last 1 hour.
This report should only contain severity red incidents. Of course it's only hourly, but it gets you closer.
I created a rule that will send out an email alert anytime it sees the severity as RED - all other fields left at 'any'. it sends out a link via email every time a high alert event is triggered. i defined the action to email me.
