Using Studio to add PVS machines to a catalog, you have to specify the PVS server and Device Collection.  Using the Citrix.PVS.SnapIn Powershell cmdlets, is there a way to do the same thing programmatically?  I looked at the PowerShell command log when doing it via Studio.  I can see the Deletion of a machine but not adding it.

Not sure this helps.
