Subdivide Surface NURBS Alpha2.52?

After creating and skinning a Surface NURBS object, I tried to create a new vertex row between 2 existing ones, but Subdivision doesn’t work.

-(Shift+R) select 1 vertex row
-Shift select 1 vert in adjacent row
-W/Subdivide (Nothing happens)

Subdivision works when I select all verts in object.

Am I doing something wrong?

Looks like the new way is to select all verts in both rows then Subdivide. Sometimes the obvious is most difficult to see.

On page 27 near the bottom of this thread Hot Project: Advanced NURBS Integration in Blender [for interested users only] You can find a post by eman that gives a link to the nurbs branch blender 2.52 build at Graphicall.org. He is adding new tools to the nurbs if you want to play with it.
