Create alert widget with alarms from only one alarm rule

It would be very useful to have a choise to “only show alerts from this rule” option when creating alarm widgets.

I have many alarms, and i want to create a widget with output from only one alarm rule.

Use case:
I have alarm rule to alert when interface is down on core routers and other important switches. I want an alert widget to show only links that is down on the router/switch.

If this is possible now. Please show me. I have not found it.
