Ability to style product detail template as a global style, as well as the ability to set a template style for a single product only.

I have a client set up on WordPress that wanted to sell a book on their website, and needs shipping fee calculated based on zones (Australia and International) and number of books (currently achieved through cart value in HL stores).

Instead of setting up a full ecommerce solution on the WordPress site, had the thought to embed a form, but forms with products added don't support shipping. Nor does a checkout form in a funnel.

So the only way to sell via HL is to do via a store, but it means directing them from WordPress website to product detail page - cannot direct to cart where product is already added.

Could replace book page on WordPress website with product detail page styled to fit in with the website, but that means other products could not be added because the product template is styled to match the book product's needs.
