I want to enable the ability to sign for and lock my work on a page, but retain the ability for others to add pages to the document being routed. Is that possible?
edit: I should specify that I've created a page where I enter info into various form fields then route the page to others to perform additional work.
No. The entire point of a digital signature is that it prevents the file from being edited after it is signed.
Imagined you signed a contract and then someone added new pages to it... That wouldn't be too good, would it? Well, a digital signature prevents them from doing that.
