[AS 3] How to disable mouse on a Sprite?

I have a Sprite with a collection of bitmaps wich i addChild and removeChild according to the script. However, i need it to not interfer with the buttons with MOUSE_OVER Sprites below.

There is a property in the DisplayObjectContainer wich is .mouseChildren, however, i want the container itself to be false, not the children (wich is only Bitmap’s anyway)

So basicly, what im looking for is either kind of a mouseChild[index/name]= false; or an Sprite.mouse = false; thingy.
