X and Y on the pixel coordinates preferences

Anyone know if it is possible to change the preferences in flash CS5 so that when i place items on the stage it will always place them on the pixel?

What i mean is when i drag something to the stage it might be set on x=33.54 and what i want is it for always to be placed at x=33.00. I want to ditch the ability to place items with the decimal point.
