Ok please contact the plugin support forum and ask them how to modify single-product template file and get on them some new options with get_option function.
“There is no template-file, which is seperatly created. wpShopGermany uses the posts (e.g. single.php). It gets the product-template via hook (the_content()). When creating a product you can select a template, which can be found in wpshopgermany/views/produkttemplates/”
