Laser Compatible?

Hello, I have a Universal Laser, and I would like to try Solidworks for designing and printing to the laser.  I need to know if there is any way to make a custom page size in the page setup.  My engraving field is 18"x32" and I need the page size to match that.  From what I have read, there is no way to use custom page sizes, but I thought I would ask here first.  We are currently using CorelDraw, and I am not very happy with the CAD portion of that software.  Thanks!
