How to Avoid a Mouse hitTest()

im creating a menu with nested MCs, of course, and the parent MC is using a RollOver action. The problem with that is: all other nested MC’s RollOver action are not detected. I know you can use a mouse hitTest as a work-around ie:

onEnterFrame = function(){
if(this.hitTest(_xmouse,_ymouse,true)){
//do whatever
}
}

but i’d like to avoid using that if possible. Any ideas? thanks!
