Mirrored Parts' Configurations

OK… I have a part and its mirror (also a part) which consists of the original part as a solid body.  Since I created it, I added a configuration to the original which I would like to show up in the mirrored one.  I've added a configuration to the mirrored part but cannot find a way to specify which configuration of the original I want… is it possible?
