Link to Part in Part Config Properties

I am using SW2013 SP3.

I have been away from SW for a while and getting rusty... I created a part file that represents a blank we purchase - generic soft jaws for a vise. I imported this part into a part and added features to create a specific fixture.

On the drawing of the fixture, I would like to link a note back to the configuration specific part number for the blank part. In the blank part file, in the configuration properties, I have the BOM part number linked to the configuration name.

So what is the syntax to make two hops to the property I need: Fixture Drawing to Fixture Part to Blank Part?

Thanks,

Daen
