Applying digital signature to multiple pdfs

We have been provided, by our client, an action which will create a signature field in multiple pdfs.  Is there a way to create a similar action which will populate that signature field with a digital signature that is located on my machine, sort of like a batch process?  Clicking the field and then placing the correct signature on hundreds of pdfs will take a considerable amount of time.  It may be helpful to note that I have minimal Javascript experience.
