ActionScript 3.0 :: Moving Button On Rollover One Pixel On X And Y

I want to move a button on rollover 1 pixel on the x&y. Here is my function:
por01_tmb_btn.addEventListener(MouseEvent.ROLL_OVER, picMove);
function picMove(event:MouseEvent):void {
event.target.x=event.target.x+1;
event.target.y=event.target.y+1;
}

I have 16 buttons I have to apply this function to. Is there an easier way to do it than:
por01_tmb_btn.addEventListener(MouseEvent.ROLL_OVER, picMove);
por02_tmb_btn.addEventListener(MouseEvent.ROLL_OVER, picMove);
por03_tmb_btn.addEventListener(MouseEvent.ROLL_OVER, picMove); etc.
