Trigger individual alert from multidimensional

Hi Guys,

I am new to grafana and I did try to find solution for my question i could not find it hence I am looking for community help.

I have configured multidimensional alert(Mem utilisation for some n hosts) and integrated with opsgenie contact point.

Actual Result:
when there is a spike in more than 2 hosts at same time, both 2 host alerts combined and coming as single alert in opsgenie
eg.
High Mem utilisation:
server 1 has used 90%
server 2 has used 85%

Expected Result:
I would like to trigger individual alert for each host
Alert1:
Server 1 has used 90%

Alert2:
Server2 has used 85%

Let me know if there is solution for this.
