AbleCommerce Shopping Cart Software

I want to set a volume discount that is structured in the following way

1 item - $200
2 or more items - $200 for the first, plus $80 for each additional item.

I don't see a way to set up this type of structure within the volume discount panel. Does anyone have any recommendations?

Im not an expert,
But paying with volume discount i did get something to work
Set the price of the product to 200
Then make a discount "Based on Quantity of line item"
Set min and max to 3, and discount to 40
Then click add row,
set min and max to 4 and discount 60

This way if they order 3 they get a 120 discount, and if they order 4 they get a 240 discount.

There may be other ways to do it.
