The request for a delay of stations has been forwarded to the team, but it may take a few months for it to be implemented if it passes. The best way to bypass this may be to use programs. You can have the A program control stations 1-4, B program 5-8, and C program 9-11 or some sort of interaction that way. It won’t be able to delay between every zone, but you can have at least 2 delays in between certain stations. Depending on when you’ve purchased your timer, you may even have a D program that can accomplish this as well.
You can have any amount of timers on your account and control them by simply swapping between stations.
