Changing XY Coordinates to positive numbers in the up direction

Illustrator uses the 0,0 point to indicate the upper left part of the artboard or graphic. I'd like to move the 0,0 point to the bottom left of the artboard or graphic where the positive numbers go up instead of down. If I want to move an object up vertically 2 cm, I have to use -2 cm. I'd like the option to choose if I want my vertical axes to move in the positive or negative direction once move my origin point. In the older versions of Illustrator the positive direction was up. It would be nice to have the option to choose up or down.
