Aggregate group of VM stats

Hello,

I wanted to get some feedback on VMAN 6.1.1.130 and how I can aggregate the stats for a list of VMs that represent an application. Looking through the admin guide, there is supposed to be a "add to app" option which I think would solve my problem. However, I am not seeing that option and I can only add them to a list, chart, etc. I need to be able to compare the utilization of different group of VMs so aggregating their stats would provide a nice comparison.

Any thoughts on how this can be accomplished?

Thanks.
