Webinar Attendee waiting message customize

[streampipemike]

Is there a way to customize the message the attendees see when the webinar has not started and the practice session was set?  Can you add logos, videos, etc.?  Right now you just get a message that says "Please Wait.  The webinar will begin soon.  Start Time and title of the Webinar and a Test My Speaker"

It is not possible to change this text/experience. 

A best practice is to start the webinar a little early, and run a slide show with interesting information while you wait for the attendees to arrive.
