You can use Personal Print Markup Language (PPML) with imposition.

PPML, an XML-based language for variable data printing, enables faster printing of variable data jobs by allowing a printer to store text elements and graphic elements and reuse them as needed.

You can create the master and variable elements of a job as a PPML file in a VDP application, and then print the job to the Fiery Server.

Impose PPML as you would any other job: Impose the PPML job on a sheet to print the pieces in a particular order so that you can cut and stack the printed job in the correct order.
