Numerous Drag And Drop Objects And Elegant Code

I have found the following code and modified it.

Code:
// Drag a piece of garbage.
rubbish_mc.onPress = function() {
this.startDrag(false); }; // When the garbage is dragged over the trashcan, make it invisible.
rubbish_mc.onRelease = function() {
this.stopDrag(); // Convert the slash notation to dot notation using eval.
if (eval(this._droptarget) == trash_mc) {
rubbish_mc._visible = false;
change_score(); } };

My question: I have numerous movie clips for the rubbish. Is there a more elegant way of calling them than repeating the above lines with rubbish2_mc, rubbish3_mc etc.
