OpsMgr (SCOM) - Powershell Get Servers in DA

I got this need to upgrade this script ( [SCOM & Orchestrator] - Alert Forwarding ) to include a new CustomField in the alarm properties with the DA name the object belongs to!
So i wondered if somehow was possible to know to which DA a specific server belongs to, and came up with this 'idea' (poweshell script!):

 Import-Module OperationsManager  
 $list = Get-SCOMClass -DisplayName "DA - NAME - HERE" | Get-SCOMClassInstance | %{$_.GetRelatedMonitoringObjects()} | %{$_.GetMonitoringRelationshipObjects()} | select SourceMonitoringObject, TargetMonitoringObject  
 ForEach ($i in $list) {  
     If ( $i.TargetMonitoringObject.DisplayName -eq 'SERVER_FQDN' ) {   
         $DA += $i.SourceMonitoringObject.DisplayName + ' || '  
     }  
}  

Enjoy :)
