Worksheets Individually Numbered When Printing

i have a program that exports multiple invoices to an excel template for ease of formatting and printing. it can export multiple invoices at once, each invoice being on a separate worksheet. i need for the user to be able to print all worksheets at once and have the pages NOT be numbered 1-30, rather 1-2, 1-4, 1-3, etc.

i understand i can use the header to insert page numbers, but they only function the way i would like when you print each worksheet one at a time. however, there could be any number of invoices to print at once. the only drawback is i am unable to use macros due to security risks/settings.

i would imagine there is some concoction of formulas i could possibly use to accomplish what i need, as i know how many rows of data will fit before excel inserts a page break(56 rows of invoice items, and there are 18 rows besides that repeat on every page). so if i could come up with a way to tell excel when to increment the page number in a cell using a formula of some kind, that would be perfect. or, another way of setting up my template so that it will print page numbers as expected.
