Is it possible to pass some default variables to the Contact Us page such as the subject line? On my product page I have a "Contact us to verify inventory" link and I'd like to dynamically add the product code to the email subject line on my Contact Us page.
Add extra parameter to the URL (with product ID), save it in the session or cookie on click and correct the fn_send_form function (app/addons/form_builder/func.php)
