Using Zen to Report Ghost Image Version

I am working to get a better handle on the desktop images (Ghost) we create. I want to be able to see the version of the image we create for the PC somewhere on the PC, AND be able to query for the image version when I am running an inventory. We just started using ZenWorks 3.2 for inventory scanning purposes.

For example, I am finalizing version 1.0 for our newest PC running Windows 2000. I want to be able to run a Zen query and determine how many and which machines have version 1.0 of the Windows 2000 image.

Any ideas?
