Using Extrude Cut to Create New Part

Is there a way to use the Extrude Cut feature to create a new part?  To clarify, I currently have a part but I want to use extrude cut feature to cut out a slot for a sliding cover.  In order to create a sliding cover, I used extrude cut feature.  I now would like to take the extrude cut geometry/dimensions to create a new part (the sliding cover) without having to re-do it from scratch manually using the geometry from the extrude cut.   Is this possible?
