Adding Users to Reach360

Hi, I have created a course that needs to be sent throughout my company. I was wondering if there was a way to only send out one email on this. It looks like if I upload the CSV of contact info, it will immediately send an invite out for everyone to join and then when I add all of the groups to the course, it will send out a second email to take the course. Is this the correct work flow? Is there a way to bypass the initial email and just send one to have the learners sign up and take the course?

Thanks!
