We are using item level discounts on invoices.  

How do I change the G/L coding of the discounts?

Right now, all discounts are being coded to a "discounts" G/L account with the gross amount being coded to the account associated with the item.  I do not want to break the discount off in the G/L, however I do want to show it on the invoice.  How can I change the coding of the discount so it will also code to whatever revenue account is associated with the item?
