Hello,
This is possible.
We have a N-up plug-in which can be used in Planet Press Watch to perform a telescoping sort on a file (N-up sorting) and therefore allow the printing of multiple logical pages on one physical page. This plug-in is not include with PP Watch by default. If you'd like to use it you will need to contact your reseller. With this tool your printed piles will follow the same order than your input data file.
However If you want to sort your data file, you do indeed need to use a vb script in Watch.
If you don't have PP Watch then the data has to be re-organized to do this.
Thank you
