Auto-adjusting scheduled times for video files

Add the ability to the Schedules feature, to auto-adjust the time-frame, when different video files are set for display. For example, if you have a 10 minute video file set in a schedule, and you would like to remove it and add a new one with 30 minute duration, the schedule to re-adjust automatically, like from the initial 8:00 - 8:10 to 8:00 - 8:30.
