Production options with multiple quantity

Hi there,
I’m after a solution that will allow custom product options/fields (this is not hard I know), so if the buyer chooses a quantity of three, my site will seek three sets of unique product options. For example, if the buyer chooses a shirt with a qty=3, the buyer can choose three different sizes. If the quantity is 15, then they enter 15 different sizes.

Is this possible??

Many thanks,
Matt
