Product Import

I need the product import tool to be modified so I can also import price breaks. Could I please get some prices on making this happen?

I am speaking of actual price breaks/quantity discounts.  We sell promotional products so for example 200 mugs might cost you $2, 500 is $1.75 and 1000 might be $1.50.  So I need to add to the import up to five price breaks per item.  My guess is that the spreadsheet would contain the lower number in the break along with the corresponding price.  So for the above example there would be six columns quantity 1, price 1, quantity2, price2, quantity3, price 3.
