Grouping Zones to Water On the Same Day

Is there any way to group multiple zones to water the same day using the flex schedule. If not this would be a useful feature as many times a specific part of the lawn is covered by multiple zones and allowing for them to be watered together would better allow for deep watering.

Water as needed would do this for you

The problem with the flex schedule is that you can’t select specific days etc. I have 10 zones and want to water each for one hour a day twice a week and to water between the hours of 2 and 6 am.
