Batch-printing many PDF-files

Hi,

In our workflow we have hundreds of PDf-files in many different subfolders we need to print on a monthly basis. We COULD print them manually... but that would be expensive, time-wise. So I figured I would make an action in Acrobat Pro X that would do the trick.

And it works... except for one thing - the "Add folders" adds ALL supported files in the sub-folders, which makes it a bit useless for our purposes. I can't see any way to sort by filetype or any way to tell it to only add specific extensions.

Is there any easy way to do this? I'm open to scripting - perhaps Illustrator might be better for this purpose?
