Pushing movieclips created by create/duplicateMovieClip into 1 movieclip?

Okay using createMovieClip I’ve created an MC called container0. Now, using duplicate movieclip & some for loops, the movie created up to 20 containers which go by the name of:

container1
container2

container20

Now is there any way (possibly using a for loop) to push all containers from 0 to 20 into 1 master movieclip?

OR

Is it even possible during the duplicateMovieClip/createMovieClip function that I can arrange which movieclip the new duplicated/created movieclip goes into?

So you know the story, I’m trying to create a ton of boxes, that I eventually want to use the image pan script on.
