setting an envdte.property to inherit from parent
I am attempting to write a VBA macro to programmatically create new project configurations in Visual Studio 2008.

I am using a hierarchy of VS property sheets to provide settings that are shared between configurations.

When I use `ConfigurationManager.AddConfigurationRow` to create a new configuration, copying properties from an existing one, I note that instead of being copied from the source configuration `OutputPath` and `IntermediatePath` are assigned default values. These are incorrect; moreover, in the source configuration, the values are obtained from the property sheet, so simply copying them to those properties in the target configuration severs that link.

What value should I write to a property or what other thing can I do that will achieve programmatically the same effect as selecting it in the UI and clicking `<inherit from parent or project defaults>`?
