Is it possible to concatenate PDF documents (each signed by a different certificate [by a different person]) into a single PDF document without invalidating any signature? I tried to join all PDF files with pdftk, but digital signatures in the resulting file were invalid. I guess that I’m trying something impossible, but I’ll really appreciate the confirmation from somebody with experience in digital-signed PDF documents.

I saw that a way is attaching the PDF files to another PDF document. My understanding of PDF Portfoliios is that they are only a fancy way of presenting the attached files in the PDF. I’m afraid that adding attachments to a PDF file would make life too hard for the recipients of the file.
