Add bookmarks to a PDF

Hello everyone, I am trying to add bookmarks to a PDF file, I create this file from several files that I am downloading to later unify them with the PDF Join activity, however I need that have bookmarks, do you know if it is possible?

Thank you,

You might have to develop a custom activity that uses iText Sharp to do this.

Could you be a little more specific or could you guide me how can I do this?

Thanks for the reply! :grinning:
