Hi Gina-
Would you know who this person is and for which individuals that they are registering? If so, you could potentially use a Custom Contact Field which could be imported into the contact prior to registration going live. I love the idea of additional custom fields with the Administrator Registration or Group Leader. I would post this as an enhancement idea on the Product Ideas page.
