I suppose territories is what they would be called, I'm not sure the wording. For example, If I want to shade everything from the middle of Arizona to the middle of Maine to the top left of Alaska, could I?

If not, I know I can add the map as a control on a form, is there a way to get the location within the map from that control? ie. 38° 22' N 81° 36' W in map coords to 100,100 control coords? If so, I believe I can shade my areas in this manner.
