Hi Coen,
Thanks for the reply. Ah I worried there might not be. To be honest duplicating the products was a last resort. Basically I wanted a number of existing products to appear with add to cart and quantity selectors on another products single product page (The company sells towels and there's a chance that while looking at one product in a brand that customers could be tempted to buy another). Related products is not in the style that we require and as grouped products doesnt allow me to do this as I can only link one product to one other I though that if I did a mass duplication I could link each version of the product (the duplicates) to one other product and get the look that I wanted while also keeping my stock in check.
