I was wondering, would it work to use the autoboom on my airdrill applications?

I would like to be able to turn off my dicky john nh3 controller a little earlier than my jd greenstar controller for the 1900 aircart as i'm approching my headland.  Would this system be able to be set for that if I seed my headland first?

(tell my if I have too much time on my hands in this -40C weather)

thanks
