Map Widget alert filtering functionality

Please add alert filtering capabilities to the Map widget as are available in other dashboard widgets.  I have a dashboard that I have constructed with the purpose to be displayed on a large monitor for at-a-glace status.  I want it to ONLY display critical alerts.  I can set the NOC Status widget using "Alert Severities to Display" filtering but I can't similarly control the Map widget so while everything is green on the NOC Status there are yellow and orange pins all over the map.  I want to have all of the pins show green unless there is a critical alert at a site.
