Is it possible to create layers in a SolidWorks .dxf export?

We currently export all of our flat patterns in .dxf format for our programming software.  We're wanting to start etching on our laser but I need another layer on my .dxf to designate what's to be etched from what's to be cut.  I'm currently going into AutoCad and manually changing it to a sperate layer.  Does anyone know how I could bypass the AutoCad step completely?
