I suggest you set “Up-Sells” products (products that you recommend instead of the currently viewed product) in the settings of the product, thus you can set products related to the same brand and show them at the bottom of the product page.
well, according your hint I’ve to manually add all the product ids of the brand, while I’d like to have either a snipped or an element to pot on the product page layout that automatically lists all the product of the current brand. Any hint?
Sorry to say but right now there is no option in Theme Settings available for that. It requires Customization and this is beyond our limitations and support policy scope. Hope you can understand our limitations.
