Hittest on ANY movie clip starting with xx

Ok, So I need help at this.

I have this script to duplicate movieclips:

** _root.duplinumblue += 1;
_root.bs.duplicateMovieClip(“bs”+_root.duplinumblue, _root.duplinumblue);**

Now You’ll be getting all sorts of movieclips like bs1, bs2, bs3, bs4, bs5, bs6 and so on.

Now I want to make a hittest script like this:

**if(this.hitTest(_root.bs1) OR this.hitTest(_root.bs2) OR this.hitTest(_root.bs3) ) {
//Actions
}
**
But that would only do it for bs1, 2 and 3, but I want it for ALL, which will reach into thousands of movieclips if a lot are duplicated, how would I do such a thing in a short line of code and NOT using a lot of OR’s
