Trying to download orders with unit price detail

I'd like to download orders with unit price, number of units, and line item total charge without the sales tax applied.  The itemization is in the order emails, but I seem to only be able to get a line item total including tax in an export file.  I'd have to know the unit price and do the math in order to import these orders into our Great Plains system.  That sounds like it's going to generate errors in tax withholding as prices change.

Can I get unit price, subtotal, and tax broken out in an export file?

Thanks

Marty
