As a former EE person...My middle school, being on a random schedule, I could still identify a grouping of time as a Period. So, for example, 8am - 8:45 on the schedule was identified as Period 1. I don't have that option in the On products which is going to make it difficult on my students and faculty. It's easier to say "I can meet you after Period 1" vs trying to remember the nameless time slot. I'd actually love to have a "period option" for Block schedules as well....but at least we can call them by the block. I have nothing for random.
