How to add another schedule as to not interfere with one

So, it was recommended to me water my lawn every other day for longer times as to develop root development. There are TWO zones which I want to water every day. What is the best way to approach this? Thank you!

I think you are saying that you have some zones for grass that do not need to run every day and then you have 2 zones that you DO want to run every day. If that’s the case, then just create a separate Fixed schedule for the 2 zones that you want to run every day and be sure to take those zones out of the original schedule.
