How can I add unique attachments to a page?
Creating unique attachment links
For example, to send each person to a different PDF, you'd need to create a customfield with the name of the PDF file. Then, you could create a dynamic link pointing to the proper file for each person. It would look something like this using Purlem's template editor:
<a href="/path/to/file/#customXXX">Link to PDF</a>
Or, if your working directly through the index.php Landing Page file:
<a href="/path/to/file/">Link to PDF</a>
