Can i set quantity for each attribute?

[billcai]

for example, I have 3 size of Large, Medium, Small for product A.

I have 10 pieces of Large size, 20 pieces of Medium size, 30 for Small size. How do I set quantities for each size?

I want, in product info page, show seperate quantities for each size, instead of a total number of units in stock.

How do i do that?

Look at Kuroi's Stock by Attributes mod in Free Addons.
