I have products for boys and girls in my shop. They are the same but I need different product images for boys and girls. Thus I created the product twice with the same SKU etc. Now the system thinks that I have twice the stock. If someone buys, stock only goes down with girls / boys. Can I adjust that there is a central inventory for both products? Otherwise I have to split the stock. But if girls are out of stock I would still be able to sell if there is enough stock in the boys section.
