has anyone here tried generating multiple pick tickets/invoices/whatever in a single pdf output? I've seen a couple solutions to this problem, but they all seem to rely on saving the pdf to a file, then combining the pdfs into a

<pdfset>

with their respective urls. I'd prefer to generate them on the fly without saving to them to a directory (which would require another script to delete them, if that's possible)

It is possible, as inside pdfset you are adding pfd and you do not need to use url you can use: <pdf src="data:application/pdf;base64,{content of file base64}"/>
