Auto loop Billboard Videos

When adding a video to a billboard, it will play through, stop showing the play button, and then wait a few seconds longer before moving to the next billboard. It would be great if videos had an option of being auto looped, so that it continually runs on a billboard, but still moves along after the intial seconds of play. This will open up the use and features of it to include graphics and message with movement that want to be on loop.
