Bulk Select "Only Me/Unlisted" Option

It would be great in 2.0 if there was an option to "mass select" all videos and then either choose to mark as "only me" or "unlisted." This would help to make sure no videos slip through the cracks to people who shouldn't have access to them in the search bar. e.g. mass select "only me" so that people on a free trial can't use the search bar to see videos not in playlists but not marked as "only me."
