Items Imported from Quickbooks Set To Non Taxable By Default

Taxable status seems to be somewhat of a sticking point in regards to synchronizing Sales Orders from Results to Quickbooks, so there are industries (like mine) that do not have Sales Tax activated in Quickbooks, so it requires us to have to make ALL active items in Results have taxable status unchecked. If there was a way to set all items to non taxable by default, then this would effectively resolve this issue.
