Union of two Bezier surfaces

Hi all,

I have a query regarding the union of two bezier surfaces. Whenever I tried to union two Bezier surfaces, rhino converts them to poly-surfaces where I cannot get the information of control points.

Is there any way to join two bezier patches so that the resultant surface is still Bezier in nature?

Thanks and Regards
