Can Alexa Start the full fixed schedule

I am brand new to Rachio so forgive me if I should ask this somewhere else. If you say, “Alexa, tell Rachio to start watering the yard”. What happens? Will this run the entire schedule? Or only run each zone for 3 minutes? or something else…

If it doesn’t run the entire schedule, is there an Alexa command that would accomplish that?

I am coming from an old style controller that had a fixed schedule (I never needed anything else). All you had to do to run that fixed schedule was press one button on the controller. I have seen that I can do this through the app but it takes multiple steps and I know my wife doesn’t even want to fool with another app.
