Two versions of event detail

I have the events app running on a site and I would like to add some additional fields to the event.html but I would like these fields to only display on a second area of events that will be secured in a members area using the members app. I understand that I can make different templates to display the additional fields. In the settings I see that the path to the events detail page is set there. Is there away to define this somewhere else for the secured events? or do I need to have them both on a single page and check for if a user is logged in or not?
