Is there a way to have a report shown on the dashboard, that shows Request Approaching Response SLA?

Similar to the Dashboard graphic Request Approaching SLA.

I can't create this dashboard report due to not being able to select a filter with

Response due by time < 20 minutes.

Am I missing something?

What I need is for the technicians to be notified when the Response due by time is approaching.

It would be great to have an alert to warn the technicians about this.

Thanks for your help
