Pass referring email campaign through to Responsys?

Hi all!

We have just revamped our unsubscribe form and are utilizing the PREF_CONFIRM log for auditing. When I pass through campaign name, it's passing through the name of the unsubscribe form and not the campaign they clicked the link from.

My form is using {'usedb':true} to give the most up-to-date information, so I can't add additional parameters there. Any ideas?

Thanks in advance!
