Automagically Populated Groups

I’d like the ability to create a group that would automatically include -and update itself- all of the elements with agents installed on RHEL 6.x systems. Or Windows. Or Solaris. Or [and I’m really dreaming here] all the elements in any OS running on Dell R720 servers.

 

This is possible in other monitoring solutions, and could be based on a relatively basic Data Store query. 

 

In short, I don’t want to have to manually manage groups based on OS.
