Easing with Drag Command

I am currently using Senoculars BeginDrag code to enable me to drag more than one object…this way i can use a custom cursor and still interact with buttons and movieclips…is there a way to modify the code to give an easing effect with the drag…below is the code…any help is appreciated…

MovieClip.prototype.beginDrag = function(target, lock, l, t, r, b){
if (typeof target == “string”){
target = eval(target);
if (!target) return trace(“Warning: Invalid MovieClip for beginDrag. “+target);
}else if (!(target instanceof MovieClip)){
b=r; r=t; t=l; l=lock; lock=target; target=this;
}
if (target.$dragMethod) target.endDrag();
target.$dragMethod = {MM:target.onMouseMove};
ASSetPropFlags(target,”$dragMethod”,1,1);
target.addProperty(“onMouseMove”,arguments.callee.getMM,arguments.callee.setMM);
ASSetPropFlags(target,“onMouseMove”,3);
var constrain = (arguments.length > 1);
var off_x = 0, off_y = 0;
if (!lock){
off_x = target._parent._xmouse-target._x;
off_y = target._parent._ymouse-target._y;
}
target.$dragMethod.drag = function(){
target._x = target._parent._xmouse-off_x;
target._y = target._parent._ymouse-off_y;
if (constrain){
if (typeof l == “object”){
t = l.ymin;
r = l.xmax;
b = l.ymax;
l = l.xmin;
}
if (target._x < l) target._x = l;
else if (target._x > r) target._x = r;
if (target._y < t) target._y = t;
else if (target._y > b) target._y = b;
}
updateAfterEvent();
}
}
MovieClip.prototype.beginDrag.getMM = function(){
this.$dragMethod.drag();
return this.$dragMethod.MM;
}
MovieClip.prototype.beginDrag.setMM = function(f){
this.$dragMethod.MM = f;
}
MovieClip.prototype.endDrag = function(target){
if (arguments.length){
if (typeof target == “string”) target = eval(target);
if (!target) return trace("Warning: Invalid MovieClip for beginDrag. "+target);
}else target = this;
ASSetPropFlags(target,“onMouseMove”,0,3);
delete target.onMouseMove;
if (target.$dragMethod.MM) target.onMouseMove = target.$dragMethod.MM;
delete target.$dragMethod;
target.startDrag(); // for _droptarget
target.stopDrag();
}
