If you would like to change the coach for just one individual class, you can simply click on the class and use the checkboxes to update who will be the coach for the class:
Then choose the name of the coach for the class, click save and boom, that class has been updated on your schedule.
But what if you need to change the coach for all of those Monday morning classes moving forward? No problem!
Then from this same checkbox screen, click on "Edit Class":
This will bring you to a brand new screen, with a lot more editing power than the previous check box screen.
From here you, as you'll see in the highlighted boxes, you can change who the coach is, so you can add the name of the new coach and then delete the name of the coach who is no longer coaching that class. Once that is saved, you can click the last toggle box, "Update All Future Classes at This Day and Time" So now, the new coach will be on the schedule for every Monday moving forward!
