Switching dimension order in vcb

Two questions.
Is there currently a way to toggle the order dims are displayed in the vcb when first creating a rectangle?
Would it be possible or valuable to make a toggle possible to reverse the order after the rectangle is created and there by re-orientating the rectangle? I often get confused on this vcb order and have to do it twice.

Me also, Now I watch the numbers in the box making sure I have one exaggerated side.
