This feature would add a new log item that can be inserted into clocks, allowing the state of a priority stream to change. This would be an alternative way of changing the priority stream state from the current method of using scheduled events. This would be beneficial for times when you wish to use priority streams on a non-regular basis. The current method would require setting up three (if you include pre-opening the priority stream) to have the priority stream active for a show, which would need to be repeated when you wish to do it again. Instead, you could create a clock for the priority stream, which can be scheduled, simplifying the process.
