If you set the time then the jobs will print in order from earliest in the day to the last. They will be scheduled by time. This will work if you are setting up a mow schedule and you know how long each job will last. However, for snow removal, sprinkler repair, sprinkler blowout I don't know how long each job will take. I schedule each job to last all day. I know it won't take all day. I want the crew to finish the first job and go to the next one. I want them to go to each job in the order I specify.
I think Jobber is working on this, but right now it cannot be done.
