How do I get custom properties not associated with a configuration in VBA?

I have a set of custom properties that are not associated with a configuration (or, if you like, they apply to all configurations that may be present and I only want to enter them once) that I need to reference in VBA.  What is the best way to get that information?

Most of the means I've found are for getting configuration-specific custom properties.  Examples are Get5 Method​​ and GetAll2 Method​.  The ones that do seem to provide access to custom properties not associated with configurations, don't give me the information I need.  For example, the GetNames Method​ will get the names of the properties, but doesn't give the value of those properties.

Is this not possible?  Am I missing something?
