I'm able to retrieve a PDF in LC repository, to assemble with another
pdf using Assembler DDX.I would also add a line of text (or edit an
existing one) in all the pages of pdf file to attach (for example, to
insert the code of the document). This text may be inserted / modified
either in the body as the header of the document, provided it is
propagated on all pages of the document.Can I perform a command such as
DDX?Has anyone another suggestion?
