Scaling Parts of Objects

Hi, newbie question here but I couldn't find an answer by searching. In the attached image you will see a simple object that was revolved from the curve next to it. My question is how to make it longer without distorting the "ball" shape at the top. I can't get the scale command to work this way. In my polygon modeler, I would simply grab the polygon on the bottom and move it down but that does not work in Moi. I realize I can turn on points for the curve, grab the bottom points, move them down and then revolve again but I would like to make this sort of change after the object has been rotated, moved, etc. away from the original curve. Sometimes this occurs several hours later after lots of other things have been built around the shape and I am trying to fit it in... Hope I'm making myself clear and any help much appreciated.
