I thought so too, at first. And I couldn't figure out what all those extra circles were for. Finally I put it all together. What you're talking about is a FAB drawing or drill drawing. Yeah, PCB doesn't have one. One thing I thought would be a neat long-term project for PCB is to have it generate a PDF that has a title page, statistics, pages for each gerber, pages for drill usage charts, drill drawings, and a full-color photo of what your board should look like (i.e. photorealistic)... etc. But not today ;-)
