Logical order for entering POP Invoice

running Sage 200 2015 and processing POP Record Invoices from the list view. When the screen loads it does not follow a logical path when tabbing between fields. The screen initially loads and appears to highlight the invoice date but then goes to the item lines. Although you can tab through all the lines the cursor then goes back to the header for you to enter the invoice details.

We would like the screen to load and follow through the fields starting with the header and then progressing on to the order lines.

When you save this screen and go to the second screen to confirm the invoice details the cursor starts on the invoice number, this has already been entered on the previous screen and should start on the second reference and should be prepopulated with the POP Order Number.
