Escalate service down - Having one notification only

Hi guys.

There are a couple of services that, if one specific service is down, others will be as well. So I would like to trigger one service as critical if others are down, and only get ONE notification instead of 10.

If service B + A + C + D are down, only send notification for service E.

Is this possible? Couldn’t find anything online. Thanks!
