Disk Space Alerts for Specific Servers

Scenario example: We have 3 clients:

1. Smith

2. Fox

3. Jones

How can set up all disk alerts for Smith to only go to Smith PMs? And so forth for my other clients?

I tried using Node Name criteria but it doesn't work inside a volume trigger.

Do I have to setup custom volume properties for all of my volumes?

Thanks

Why doesn't this below work - ?

Edit - I think I see why now... https://thwack.solarwinds.com/message/232025#232025

Edit - resolved.
