Is there a way to link a Configuration specific custom property to the "PART NUMBER" property that is displayed in a BOM?

We are using a third party CAM program that reads a SWX configuration specific custom property value to use for the machine file name.

I can create a configuration specific property called "PartNo" and edit it manually for each configuration, but it would save a lot of time if I

could link it to the "Part number displayed when used in a BOM" property, which is already set up via the configuration property tab.

(right click on a configuration & select properties, Bill of materials options.)
