Yes, please contact webinar.net support to enable the feature for your account.
An attendee controlled, or interactive, presentation is one which allows your audience control of advancing slides. The audience decides which slide appears next and how long each slide remains onscreen. The audience can browse from slide to slide at their own speed.
When enabled, clients will see the attendee controlled slides switch inside Interface Builder’s Presentation component.
