Arduino Components and PCB

I have laid out a generic Arduino Shield as a .BRD file in Eagle Cad. After drawing an Eagle schematic of a circuit. is there a way to use my Shield .BRD with the schematic when I press the Board icon on the Schematic view? I have an Arduino componet that I designed, but it is hard to use because it is necessary to position it accurately on a properly sized board using it (the component) on my schematic.

Any enlightenment will be appreciated.
