How to modify the page numbering in RTF Template for printing different invoice copies

I create RTF tempalte using BI publisher to print an invoice, with different copies in the same template one for the customer one for the warehouse and one for the Fianance team, i need to use the Page numbering, but i need each page to start the numbering from the begigning for each copy, that's mean if the invoice will be printed on 2 page so the page numbering for the customer copy will be 1 of 2 then the starting of the Warehouse invoice will start with 1 of 2 same for the finance copy, not to be shown
