Hi, I'm trying to modify this module for using it in the Greek system. In the greek system the only thing needed it to select if you want invoice or receipt and if you want an invoice to write the company infos. I would like to show these options in the position marked with red in the attached picture. I don't want to show the options on every available payment method. So let's say in this page I want the customer to first select if he wants receipt or invoice and then to select the payment method.
Would this be possible? How can I achieve this? Which files do I need to modify?
