Limiting user's access to the defined alerts

Hi every one,

I am working on vRealize Operations Manager version 6.2. I created various groups and each group has diffirent permissions. I defined alerts for each group ( each group wants to see a diffirent kind of alerts). The problem is that I want to let the users to read only their alerts in the summary page not the alerts of other groups, and in the administration area, we can only say if the user can read or not all the alerts, there is no way to associate an alert to a group of users. I want to know, is it possible or not? How can we do it using PowerCLI ? Thank you for your help.
