Product customisation needed

[Parag]

Hi,

 

We have a product like cardstock pack. Each pack have 6 cards. Customer can select colors for this 6 cards. He can even select single color 6 times or 6 different colors or any other combination.

 

I tried attribute combinations but it only allow to add single colors at a time. I want there to be only 1 entry in the cart with color names as attribute.

 

something like this http://papermilldirect.co.uk/acatalog/Mega_Box.html

 

Has anyone developed any addon/module for this? Anybody interested in developing?

 

Thanks
