Best Software MAS90 Code

MAS90 currently uses LAST COST to calculate the sales price on a "cost plus markup" item. For Instance: Inventory cost tiers show these item in inventory for item #1234 5 at 10.00 ea 10 at 10.50 ea Inventory valuation is $155.00 (correct). But when you sell 6 of these items (even if the system is set to FIFO) the sales order module calculates 6 at 10.50. I need it to calculate 3 at 10.00 and 3 at 10.50. We do not have the MAS90 code, only master developers do. We may be able to do this using the crystal report designer and a couple of user definable fields, But I need some help to see if it's posible.
