This is a very noob question but I couldn't find an answer anywhere for this.  I have a bunch of doors in a factory and want to array/pattern a door along the wall so that I have multiple doors.  I saw that there is a PowerCopy tool but according to this video, it copies floors and other objects on a level.  It looks like there is a pattern for Wireframes, Surfaces, Solids, and Functional but nothing let's me copy multiple door Sets.  If someone could point me to a video, that would be awesome!
