Relating Custom Properties to Configuration Specific Properties

Hello All--

My company is starting to use workgroup pdm.  We always used configuration specific properties and the vault only maps custom properties.  Is there a way within the part to set custom properties equal to configuration specific properties?  Is there a way to do that in equations? 

I have tried to set a property equal to a global variable and use the global variable in custom properties, but the values do not update.  Attached is the part and B is the global variable for the specific property. 

Any suggestions?

Thanks.

Sincerely,

Chris Sparber
