Sounds like a good feature upgrade in the future. You should create this as an Idea on the forum.
We have used Adobe Acrobat Pro to merge multiple PDF files together into one. You can do a 30 day trial of that from Adobe. I know the program is somewhat expensive and I am sure there are many free or nearly free utility programs available on the Internet to do the same task.
It is a pity that this is no current feature. Maybe it could indeed be considered for a future release.
Thanks also for the heads-up with acrobat. I would need a process that makes the bundling of the PDFs 'batchable' - otherwise there is a new manual step in the process of report generation that will reduce the appeal of an NPrinting solution to my client. Maybe I can dispatch the reports to a Pdf printer and somehow group the individual components by the cycle field prefix... Still it is a bit botched .
