If you're a user of the Organization Portal you can get access to a new option (reach out to your customer success manager to enable it) when creating an event.

This option will display all of the event's session on your organization portal, rather than just showing the days the event is running.

Click into the session from the portal page will show a new session details page. This page has a unique link that can be used to direct potential attendees right to the session details page, designed with corporate Intranet, wiki, and directed communications blasts in mind.

To display an event's sessions rather than its dates navigate to the Event tab, then the Details menu item and select "Display session time slots on portal...".
