We know that unexpected schedule changes can happen. If Pathful is still looking for a presenter, and the session appears under Requested in My Sessions, you can update the date options. The two-week window does apply to updating these sessions.
If you need to add dates within the two-week window, contact support through the purple "chat bubble" on the lower right corner of the site.
If your session is already confirmed with a presenter, you can not update the dates through the system and must reach out to the support team.
