Quantity box for each custom field - modification Help

[gete]

Hello to everyone this is my very first Post and i hope to explain well the modification i need.
joomla 2.5.9 | vm 2.0.18a
For example i have 1 t-shirt with custom field (Type:string,cart attribute:yes,is a list:yes) the list is for size (s,m,l,xl)
i want in detail page to have every option with their own quantity box so if i want to add in cart 2 small t-shirt and 3 xl i will write in quantity boxes the right quantity and then i will press the add to cart button to add all at once. Otherwise i should select the radio button of small t-shirt write the quantity and press add to cart, then select xl write the quantity and then press again add to cart. Imagine do this for spray colors with a variety of 200 colors. When someone wants to buy 20 different colors, he would press add to cart button 20 times instead of one.... this is what i want to fulfill.
Is this possible;
Where i should start with the modifications;
thank you in advance.

Hello, Gete -

What you describe is not an out of the box feature for VM, and is not easily achieved with an answer in the forums. I think you will need to hire a developer to focus on designing out and developing a solution to customize your VM2 to have this functionality.
