DXF layers from sketches?

I have a .sldprt that contains several sketches, all on a common plane. I'd like to export these as a dxf with each sketch as its own layer. I've tried making a drawing of the part and assigning layers to the sketches, but can't seem to get the individual sketches to move to the new layers. I also tried exporting with mapping, but that puts all sketches on the same layer. If exporting directly isn't possible, maybe there's a work around?
