Disappearing dimensions

REVIT, why do you think that just because I delete an item, I'd also want the associated dimension to disappear? I mean, I just might want to draw a new item, and NOT have to redraw the dimension. God forbid I might actually forget to draw the new dimension and then cause a problem down the road. Please...no disappearing stuff please please please please. You have taken away my control of my drawing. SUC*!!
