How to Print T&C on backside of the last page in smartform.

Hi All,

I have requirement from one of the my client to print the terms & condition page on the back side of last page in invoice form.

I have created three pages as below.

First page: To Print header data,Print mode:blank,Next page : NEXT.

Second page : Contains the continuation of the data,if there are enough lines,Print Mode: D,Next page : NEXT.

Last page:To Print T&C,Print mode : blank,Next page :blank.

This is working properly when form has 2 pages.Here my question is,

How to print the T&C on backside of first page,if form has only one page.

Thanks in Advance.
