To use the same code for many movieclips

Dear all.

I am using the flash to build my personal book online. I need zoom  many movieclip, my images.

i make the code and function perfectly. But I want to find a way to use the same function for all movieclips and so, mantaining my code clean.

mc_01.addEventListener(MouseEvent.MIDDLE_MOUSE_DOWN, Drag);

mc_01.addEventListener(MouseEvent.MIDDLE_MOUSE_UP, unDrag);

mc_02.addEventListener(MouseEvent.MIDDLE_MOUSE_DOWN, Drag);

mc_02.addEventListener(MouseEvent.MIDDLE_MOUSE_UP, unDrag);

and many others....

function Zoom(e:MouseEvent):void

        {

        mc_01.x = 0;  //I try here for this.x but the previews movie, called "Books" is who have changed your x value.

        mc_01.y = 0;

        }

I

EDIT: For untangle, the previews movie is called MyAllPhotos and then, contain all movieclips that are each movie clip is one my images
