Rick, thank you for the suggestions. After thinking about it some more I realized that for one of my Pan cams this didn’t matter much since it’s on pan scan 24/7 with motion tracking also enabled. Even if it’s power cycled it returns to pan scan and motion tracking after booting.
For my other Pan cam I was going to write a large paragraph explaining my situation with it. However, after composing most of it, I realized that my problems can be solved via a method that is the topic of another #roadmap discussion regarding adding more actions to shortcuts. Also, I see that turning on/off detection zone is already on that list. I hope most or all of those suggestions get implemented. 
The suggestion in this thread is still a good one. Perhaps have the middle d-pad slew cam to the set detection zone? Thanks again Rick.
