Discount Column Changes

Hello Members,

I have an doubt in the quotation module where I want to reverse the Discount Column in Product line items to Service Charges or Delivery Charges line items and the logic hook of Discount Column is having AMT/PCT which will reduce the Product Price in Grand Total but what I want is I want to increase the Product Price by adding Delivery Charges in Grand Total.

From this above image if i add the price in Discount Column the logic hook will work in an subtraction one but what i want is i need to sum the Discount Column.

Can Anyone help me how to achieve the above request.
