Epson 5010 Adjustment Question

[Movie Man Don]

So here's the deal.
My 5010 is dead center of the screen left to right but the vertical center point is about 3/4 toward the top side of the screen. Not enough to cause any keystone problems.
Is there any adjustment/setting on the 5010 which will allow me to zoom from 2:35 to 1:85 without manually re-adjusting the height of the picture. Bear in mind that my screen is constant height and moveable side making. It doesn't take long to adjust the picture height going from one ratio to the other but I thought it would be really nice is there was a way to keep the picture height constant. In other words, going from flat to scope without adjusting the picture up or down.
I got a feeling I already know the answer to this but it never hurts to ask the experts and there are a lot of you guys who know the answers.
