We've added support for allowing site admins to create custom PDFs for delivery to a target. This allows the site admin to create a Delivery PDF with specific fields.
To use this feature visit: Admin Area > "Your Petition Name" > Custom Petition Delivery PDF.
The signature fields to be included in the custom PDF can be defined on a per-delivery PDF basis.
This feature is great for cases where you might want to include the email address or other sensitive information while delivering a petition -- which is not exposed in the printable Delivery PDF by default.
