Manual Run By Precipitation Rate


It would be great to be able to run a manual watering cycle to hit a specific amount of precipitation. For example, after putting down some lawn products you are supposed to put down 1/4" of water. My lawn has 3 zones and each have a slightly different precipitation rate based on my testing with catch cups. Instead of doing the math from each custom nozzle to figure out how long I need to run each zone it would be great if there was an option to have the system automatically put down 1/4" over the selected zones.
