Multi Thermostat Scheduling for Control of Peak Demand

I have a home with three separate HVAC systems, each of which is controlled by Honeywell thermostats. I successfully added them to ST the other day with no issues and am wanting to set some logic in place that limits the systems from all running simultaneously at any given time. Reason being is that I am on a time of use electric rate that looks at peak demand. I considered just creating alternating scheduling blocks to accomplish this but wanted to seek input of others incase I’m not thinking of something a little less time consuming.

New to the community so forgive me if I’ve posted my question haphazardly and in a poor category location. I searched a good bit for a potential answer but didn’t find exactly what I was looking for. Thanks in advance all.
