Edit each invoice's pages

Hi,

I need to be able to edit 3 pages for the same invoice. This way, I will put all the DebtCategory on one page.

On the second page, I need to be able to just show each item that are expenses.

On the third page, I need to be able to see all the item. For the moment, I don't know how to add a 3rd page to the invoice and I can only choose the Debt Category for all the invoice, not by page.

Can you help me?

Thanks,

Marie-Noel Filion
