Daz to Unreal Bridge FBX export does not include smoothing groups?

Is the fbx exporter that is part of the Unreal Bridge missing an option to include smoothing groups? When I send over geometry with the smoothing turned off or at a low angle (for flat geometries like walls or table tops) they come into unreal with a smooth applied. Even the Unreal log mentions that it could not find smoothing group information in the fbx and instructed me to turn it on in the fbx export options, but I did not see any in the daz fbx options.  Any ideas?
