Move vertex without change UV map (like old behaviour in blender).

Support Materials and Textures

In older versions of Blender you can do things like:
• Make a cube
• UV map it
• Subdivide
• Move the new vertex without change the UV map (Example: To make and move a hole in the cube ).

Now you can´t, and is very hard to me to make corrections, or add geometry, after mapping mesh, i must re-mapping it.

Is there any solution to it? Perhaps an add?
Thanks
