Jotform App: Product list add shipping costs?

I can't find how to enter the shipping costs in the product list included in the APP that I show below

Hi Holidea,

Thanks for reaching out to Jotform Support. There's no option to add a shipping cost to the Jotform Apps Product List.

I will forward this as a feature request to our backend team so they can check it further. We’ll get back to you as soon as we have an update.
