I would like to see an option added to Offset surface (that would appear when more that one face or surface is selected) that would be labeled "Single Surrface" when  checked, would be able to copy (zero offset) or offset the surface but instead of offseting multiple faces would copy or offset a new single face - i.e. one complete surface body with no internal edges. 

this would be very useful in creating strink wrap packaging for Point of purchase as well as simplify the surface modeling process by simplifiying there model's topololgy.
