I have a document that I want to attach a file. I go to Tools -> Comment -> Attach File. I've selected the file that I want to add, then I'm given the choice of icons that I want to represent that file on the document. THIS is my question. The Graph, Paperclip, Attachment, or Tag icons don't really appeal to me - I would like a different icon. How do I do that?
May be not possible.
Instead of using the annotation tools, could you use the "Edit" pdf tools. You could place an image on your page for the icon, then create a link to the attached file as an overlay.
