Quantities for Attribute Selection

[sek]

Is there a way to set individual quantities for items that may have multiple options.

 

For instance if I am selling a tshirt with one design, but it comes in Small Medium & Large, and I use the product attribute for the user to select via drop down box which size they want, can I in the admin section somewhere put that Small - I only have 10 on hand, but Medium I have 15 an so forth?

 

I would hate to have to have a separate product listing for each size, that to me seems silly.

 

Is there a contribution to do what I am asking?

 

Thanks in advance,
