Import fields from winestro

Hello,

unfortunately for my level of knowledge, I am at a dead end. About my knowledge level: I would rather call myself a web designer, so very superficial backend and PHP knowledge.

I maintain a webshop that imports products via a third party system (winestro), which works good so far. But I have a problem and a aswell question:

I want to import certain fields with template hooks to comply with German market requirements:

1) In product listing: liter price (wbo_literpreis) to each price. Currently the store pages are created manually with the page editor, as custom elements are still placed below and above the product listing.
To insert wbo_literpreis there are two possibilities as far as I know:

A) "Native generated" store pages from Woocommerce.
-> Problem: I can't insert individual elements for each product category (category title and description for example).

B) Self-generated store pages with the page editor.
-> Problem: There is no template hook for "Products by Category".

-> Is there a solutions for this?

2) Product detail page: "wbo_zucker", "wbo_zucker" and others.
Question: is there any way to play out the data in the "Additional Information"? With the template hooks I can only get to other places in the template, so the information would end up being very scattered on the page.

Info winestro fields:

I really hope those things can be solved.

Thank you in advance!
