Only one discount per Product

Hi,
I have this question. I want to create coupon code but only one product to be discounted inside the cart. If the user add for example 2-3 products I want the coupon to discount only one product. Right now they can add 5 products and the discount will be on whole amount. I don't want this. Is this possible to do It?

Use value defintion:

qty value
1 your percentage discount
2 0

Where i need to put this Value definitions? In which field?

I found it :) thanks
