A simple interface allows you to define part of an order with several sheets as saddle stitch and that partial product later on as perfect binding. Just a few mouse clicks allow you to group together several sheets in an order and separate them visibly from the other sheets of the order. These grouped sheets are displayed in the sheet list indented giving you a clear overview.

The fact that each individual sheet in the sheet list now also displays the corresponding page numbers may be seen as another small detail to further clarify the clear layout for orders with large numbers of sheets.
