With this new feature added to Social Rotation, you have the ability to run the content bucket just one time.
In order to use the new run once feature, create a schedule like normal, then move the run once toggle over to right. Any schedule that is using that content bucket will then be a run once schedule as well.
Once the content bucket has posted all of the images from that bucket, the system will automatically turrn off all schedules that use that content bucket.
