Ok, I'm not sure if anyone else has any need for this information, but I thought I would share how I ended up doing it. I created my own custom module for the site, and did a hook_form_alter. Then I had to use hook_nodeapi to save all the information and retrieve it when necessary. Of course I also had to create a database to hold the information. Anyway, if anyone wanted to have a look I've attached the files instead of just copying and pasting the code here.

Cheers,
Steph
