Is there a way to move textbooks between accounts?

Before you start, please note that each account can only have one textbook from each grade level, and tracks a single student's use information. When you move a textbook, it saves the usage and score information of that textbook, so no work is lost.
To move textbooks:

Write down the textbook code of the textbooks that you want to move.
Select the correct code on the left hand side and click "unclaim".
Log in to the other account and claim the textbook using the textbook code that you wrote down.
