Adding sub headers in the product payment field

Hi

I am trying to use your product template. In the section where I define the products, it allows me to create several products. This section has a header. In the attached image, I have called it "Portfolio Boxes" - I would like to be able to create several of these sections, each with a different header, as they relate to a different sub-set of products. So in the image, I would like to duplicate the entire section in the blue outline. Or alternately be able to add a heading between products?

How can I do this?

many thanks

You can only add one payment field in the form. A workaround would be to add the category header with zero price then style and disable its input by CSS. Here's a guide for that:
