add users based on databases

I have servers with multiple databases which belong to different departments. I want to share some Diagnostic Manager Info with DB owners but not the whole Server Information (i.e. Dashboard).

In application security I can only assign whole servers with users. As multiple users owning DBs are on this Systems I cannot do this. I will share some reports like "Database statistics" or "query statistics" with them. Is there a way to define alerts which are only triggered when metrics of specific databases are affected- like database Status or deadlocks

Or any other way to provide users of shared SQL Servers with diagnostic manager based information which are related to a specific database?

Thanks a lot
