Batch Bitmap conversion to Sprites?

I'm looking for a method or tool that allows me to make the follwing:

import several bitmaps(pngs that are frames of an animation) convert each of those bitmaps to a sprite, put each sprite into an array in order (spriteArray_name.push[bmpSprite]).  The array itself can be just exist as a static array in resource file. 

This isn't exactly a complex task, but I've got THOUSANDS of frames for different animations, and I really dont want to do this by hand.  I'm not an AIR programmer but, would that be a possible easy solution?  It just seems like there would be an easy way to Batch this process.

I'm currently using Flash Pro cs5.5 for the project.

Thanks ahead of time,

EDIT:

I am currently doing this at runtime, basically creating empty spites and drawing in the bmp data on the fly.  But, its not going to work. I need to do this precompile (or during compile if thats possible).
