When adding new configurable products, I want to enter two prices. The normal price, plus a cost price (the price the item cost me).
I've added a product attribute for costprice. When I create a new configurable product, I can enter the new cost price for the item. However I want to add the cost price for the configurable products as each configuration can have a different cost price.
For example, image creating a t-shirt as the product and having different colours as the configurable items. I can enter a cost price for the t-shirt, but not for each configurable item. When the configurable items are generated, I can edit each of these 'virtual items' and enter a cost price, but I would like to enter the cost price when I enter the configurable item price.
