Live Zoom interaction with customers while building course

When I work with a customer on their course,  I setup zoom meetings with them and share my screen so we can edit the course together to insure the time spent designing is spent efficiently, instead of going back and forth several times and producing many betas.  While on the Zoom meeting they tell me exactly what they want and I do it on the fly.  This way there is no question as to what they are expecting.
