Using program RFFOUS_C to print 2 Checks / Advices per page

Hi,

We use 11 X 14 perforated check stock when printing our checks with a 3rd party program, this current program prints 2 advice's / checks per page separated by the perforation.

We now want to use program RFFOUS_C, we have made a copy and customized it to use a smart-form. It currently is printing 1 check advice and 1 check per page. How can we change this so that we will get 2 advice's / checks per page separated by the perforation.. Not necessarily the same vendor for both checks. Is anyone doing this? Thanks,

Jim
