The total from the lines on page 1 shoudl be shown on the bottom of the page 1 and on top of page 2 and than add subtotal from page 1 with lines form page 2 shoudl be shown on bottom of page 2 and so on.
The subtotal of each page shoudl be carry over to next pages.

The aim is to provide the customer's customers a sub-total per page, if the lines go over more than one side.

Currently there is no option under GER to have such subtotals and for now the only suggestion is to check Word capabilities to do it.
