product options with quantity boxes

I haven’t found this anywhere within cs-cart as standard, so i’m assuming it will need to be a mod…

My products have have an option of “Color”. I need to have a quantity box beside each color choice so they can add multiple colors to the cart at one time.

My other product options should not have quantity boxes. For instance, a product option of “size” should not be followed by qty boxes, just color.

Can anyone tell me if this is available or not ?

it has to be a customized mod. cs-cart gave me a quote for it, but I actually choose another cart for that project which had it built in. I think their price was $200-$300 or something for it.
