Zoom for Online training several users

I own an online school where use Zoom for our students. We have several classes at the same time and the teachers are not considered as users on our Zoom account. It's difficult for us to start the classes for each teacher and then make then a host. Is there a solution where the teacher can start the meeting directly once schedule by the school on Zoom? We have more than 5 different teachers and they have each 2 hours a week.
