Pump relay control for each zone options

Appreciate everyone’s input. While the timer and relay solutions are a workarounds, I’m having a hard time justifying the added work and/or upkeep for something that can be implemented so quickly through a software upgrade. I understand others may feel those are viable solutions for them and that’s totally fine, it’s just not for me. I just returned it to Costco and will stay with my existing set-up. I’ll check-in every once in a while to see if anything changes. Thanks again everyone.
