Hello All,
WE have a project where I am confident that PP can help greatly simplify our workflow:

We are doing mass mailings and have a "pre-merged PDF" which we are trying to print 3-up. The issue we're having is that we need to stack the 3-up according to subsets of the CSV file (these are mailing trays) and name them differently as output (the file name will be the tray number from the CSV). We're using an Emulated Data Splitter to subset the data without issue.

Since we're not merging any of the data to the document, how can we get PP (Design or Watch?) to identify which page of the PDF needs to be the next nUP record? I've proven that PP can do the stacking as needed, but can't figure out how to hand the document the right page of the PDF.
