@SusanBradley Sorry, currently there is no way to do that.
We do understand that there is some very stringent restrictions in place. At this time, the only way to guarantee that your schedule won't trend up when warmer weather appears, is to disable the water budgeting feature on your watering time.
You can still leave the weather intelligence feature which will skip schedules based on observed and predicted precipitation.
Thanks and have a great day!
