It's possible, but you realize that the extracted page will not be signed, right?
Oh really? That's so odd! I can set up a button that extracts the page with an inputted signature, but I suppose that since that will be digitally signed, it will not work that way?
What I'm thinking is that when I digitally sign the document, it saves a new version of it that IS signed. I'm hoping to do that for just that exact page and not the entire document.
You should do it the other way around, first extract the page, and then
have the user sign it.
