I have a message I want to show up under the payment info when the user selects one of the two offline payment options I have set up. Just to give them specific instructions for those options.
Unfortunately, we don't have a way to config the extension to make it works like that. So if you want this feature, some customization will be needed (I think it is javascript modification). You can submit a support ticket and we will be happy to help you with this small modification
