Hi @CindyCFFP,
There are two ways I know of to tackle this...
- As you've already basically mentioned, you can extend the course dates, add the person, have them accept the invite, then set the course dates back to the original. If you can coordinate the timing with the person being added, this only takes a couple minutes, and students probably wouldn't notice the course being back on their dashboard for that short time.
- If you're an admin, or know your Canvas admin, they could add the extra person via an SIS import csv file, which wouldn't require the course dates to be changed, nor would the other person have to accept the invite.
Hope this helps a bit. Let us know if you have any other questions or need clarification around this.
-Chris
