Is it possible to change the direction in which the numbers grow on the rulers?

Newbie here.  I'm going to be using Corel with a laser cutter in which the origin is in the upper-left corner.  It would simplify things if I could configure my drawings the same way.  I figured out how to set the origin up there, but the y-axis increases negatively down the page from the origin; I'd like it to increase positively in that direction.  Is that possible to do?  Thanks.
