Need a button to insert multiple page document in fillable form.

We are creating a fillable form for our employee files and because most of the people we are hiring are not going to have DC pro, let alone know how to use it, I am looking for a way to include a button that will allow our branch administrators to insert pre-hire paperwork through out the employee file.  I have included several buttons that allow one page documents to be added, however some of the documents are multiple pages, such as our application, and will not show or print the extra pages once it is inserted.  The problem with adding a page/button for each page of the item to insert doesn't always work either, considering some people might have  a longer work history than others. 

I have also tried to include a button to insert attachments, however they will not insert into the actual document, appearing more as a note, and will not print with the rest of the pages.
