Feature Request: Only show Pre-Roll for first video in watch session.

[dfine321]

I would like the option to only show the pre-roll for the first video in the session. I use it to make sure the volume loudness is where i want it to be, so the first video is the only one that is important per session. (would be especially useful for tv shows)
