ZC_Subject & ZC_Content but is there a way to capture FROM or TO or CC?

Hi there,
I am using a form with the ZC_Subject & ZC_Content to capture the subject and body of the email.  is there a way to capture any other parts of the email?  Like TO or FROM, or better yet a unique header id?
Thanks,
David
