The event page currently does not offer an option for sponsorships specifically. I'm aware of the "work around," however the verbiage the visitors see on the event page is somewhat confusing, especially if one of the sponsorship opportunities DOES NOT offer tickets to the event. My idea is to make an option in the "Configure Ticket Types" section of the event creation page indicating whether or not the "type" is a sponsorship or tickets. If the sponsorship includes tickets to the event make that a "Yes/No" option, how many, etc. This will eliminate any confusion with verbiage, additionally it may help organizations, like mine keep better track of sponsorships purchased as opposed to tickets.
