Export SubD flat (box) mode to OBJ

Hi there!
Is there a way to export the flat / box mode of the SUBD model to OBJ.?
This would be great because than you can import it into you polygon model software and add a smooth modifier.

Closest I got so for is to crease the entire model and export that. But your model will still have unwanted sub-faces.

To export the SubD control polygon, select the export options highlighted in the image below.

You can also run the ExtractControlPolygon command on the SubD.
