Two valves in the same line

I just installed an Inkbird 600 irrigation controller.
I want valve 1 to operate zone 1 to run my drip system for 4 mins, with a secondary valve (2) in the same line so that while valve 1 is open valve 2 will open for 2 mins. Can I schedule that. I’ve tried scheduling the corresponding times as well as “multi zone settings”, neither worked.


Sorry, IIC-600-WIFI can only open one zone at the same time.
