Allow all submissions to be filled out at once from the form signing screen

You get an email every time it is your turn to sign a form. The only way that you can get to that signing screen is to use the link inside of that email. Therefore, you are "authenticated" and considered authorized for that particular email address since you had access to the original message with the link. With all of that said, we can add a sidebar to the signing screen that has a list of all the forms where that email is the current signer. This will allow the person to fill out all forms waiting on them without having to search for the corresponding email for that submission.
