Request Additional invoice fields Discount Total

Hello Invoice Ninja team, first of all thank you for this great software and I would like to request few things regarding invoices.
In many cases bussiness and me myself have need to show what is the total discount of invoice.
Now if I add percentage or sum of the discount on entire invoice I have field on the bottom telling user what is the discount amount he got. (See pic 1), but when I add discount on product itself that field is not displayed just calculated in line items (see pic 2).
Can you add this field so I can have that field displayed on the invoice itself.

Thank you!
