Setting movieclip origin with AS3

I have a spotlight that moves on a stage. Now I rotate the spotlight but its not rotating on the correct point/origin.

I am trying to do something like

myOject.setOrigin = {x , y};
//and then rotate it about x,y.

I have manually set the white circle in the correct place and when I rotate the object with the mouse on the screen it works. Can somebody help me?

If your MC has multiple items per layer, group each layer before aligning, then ungroup after aligning:
