Combinations: how to sell a box with 6/12/18 items and keep the single-item price right?

[Bruz]

Hi,

I'm selling wine. For some wines I'd like to sell boxes with 6/12/18 bottles only because of the shipping. So I've created a group called "box size" and attributes names "6", "12" and "18".

Now if a customer chooses "box size: 6", the system should put 6 bottles of the wine in the cart, but whatever I fill in as Quantity only one bottle is added to the cart. When I put 5 times the price of the product the "Impact on price" field it adds up, but that price shows up everywhere else as the price for one bottle - is there a way to chnage that?

Hi Bruz,
This is very interesting, since I would love to have a way to add boxes as an option, and it would be amazing if we were able to do it with radio buttons, something like this:
