[Vantage 8.03] Combined pricing for sales orders with multiple ship

Is there a way to set Vantage up to combine pricing across all ship to addresses for a specific order?

For instance, for product A, we have price breaks set up for quantities of 2,000+. If a sales order is entered where we have 1,500 of product A shipped to address X and 1,000 of product A shipped to address Y, the customer does not get the price break. I know that we can manually do a price adjustment on the order, but we would like for Vantage to automatically calculate the price break, regardless of how many shop to addresses are selected.

Anyone else experienced this issue or have any ideas for a resolution?
