Shipping: Basic Price?

Hey Guys!

after spending hours on setting up shipping costs the way i need, it looks like this isn't possible with cs-cart?

I need a basic shipping amount like: 3$ for a single product.
if a customer want this product 6 times the shipping costs should be 3$ + 5 x +0.1$ = 3,5$

Looks like this isn't possible out of the box?

So if customer has in cart 5 products A and 3 products B, final cost should be

3$ + 5 x +0.1$ + 3$ + 2 x +0.1$ = 6.7$ ?

If yes, unfortunately, it is not possible in CS-Cart
