Well obviously the answer is yes. Most people would probably do it in their CAD package. If you want to use a third party tool Fab3000 does tis as well as a whole bunch of other things you might possibly want to do when processing files supplied by other people that you want toget manufactured and then populate. e.g create stencil layers with custom apertures, create pick and place files from Gerber data etc, its not super cheap to buy but you can rent the whole suite month by month if you have intermittent need.

I've not used it but google also brings up this free tool, that appears in fact to work with raw gerber data despite mentioning Kicad all over the place..
