How can I call a PDF attachment inside a Custom Crystal Report?

I am using Crystal XI with a custom report that I have made. I am using a SQL 2005 DB. This report is pulling over 100 different tables from the database.

I have PDF attachments being added to the records in a separate table. The attachment table is linked to each specific record correctly.

I am trying to find out how when the report runs it will display the attached PDF inside a sub report inside the main report.

Is this even possible????
