We have created an invoice where it will fit 15 detail lines per page. But a number of the invoices will not be 15 lines but will be 1, 3, 5, 9 whatever.

As per the screen shot attached is there a way to continue the numbering down the left hand side to max out at the 15 detail limit even though there are not 15 detail lines in the invoice?

Hope this makes sense.

Thanks in advance.
