Add New Columns to SOP and POP Lists to quickly show the Value of Goods Despatched (SOP), Value of Goods Received (POP), and Value of Goods Invoiced (SOP & POP) for Partially Recd/Depd/Invd Orders

It would be great to get new columns on the Sales Order List and Purchase Order List to show the:- Despatched/Received Value (SOP) showing the value of goods that have been despatched only on sales orders and the value of goods received only on sales returns.Received/Despatched Value (POP) showing the value of goods that have received only on the purchase order and the value of goods despatched only on purchase returns.Invoiced/Credit Value (SOP and POP) showing the value of goods that have been invoiced only on sales and purchase orders and the value of goods credited only on sales and purchase returns. This is a very common query I get from our Sage 200 customers and I've not found a quick answer for them other than directing the customer to run a POP report instead or writing something for them. The general feel we get is that customers expect these abilities out of the box. Even some of the reports available show the sales/purchase order line full net value.
