title: Tcpdf multiple signatures
body: <p>I am generating PDF files with tcpdf. So far, everything is ok.</p>
  
  <p>I understand that it can only have one digital signature and it has to be created at creation time.</p>
  
  <p>However I have some PDFs that have to be signed from multiple people and, not simultaneously. My app can generate different PCKS#7 signatures when each member decides to sign the text. </p>
  
  <p>Is there a method by which I can add those multiple signatures by some raw insertion function? I do not need tcpdf to generate the signature, just put it to the file.</p>
  
  <p>Best regards.</p>
