Would it be possible to add adaptability to the discounting feature in the invoice module? for example I might want to discount on a per line item basis or on a per invoice basis whereas at present I can only change the customers discount globally (and then have to remember to change it back again!).
Also, if discounting on a per invoice basis, would it be possible to add the discount into the Totals section below the line items - presently if selected the discount is indicated in brackets on each line item (which is ugly) and the customer can't see what they would have paid had the discount not applied.
