How to make an action batch process a large group of PDF docs instead of individually

I'm using an action containing a script from the Acrobat Exchange (specifically the Stamp and Number Document action). I've modified the script a little to make it do what I need specifically, and it works great but I need to process a few thousand PDF document. The action brings up a dialog box with options between each file. Is there any way that I can easily make it take the original input parameters and run with it for the whole batch? Otherwise, I would be clicking the process button for each file without changing anything. I am not a script writer at all but I usually can modify what I need to make it work but this one in particular is large and I'm not sure what to change or add. I appreciate any help I can get and thank you in advance.
