Adding a thatquiz standard math question to a test in design

QUESTION
Is their way to import one question from the concept section that uses the moveable ruler to your own test in design?

ANSWER
There is no way to import one question from the concept section into a test of your own design.
However, after a test is assigned to a class, and before any students have tested, you can add more questions to it.
You can merge two tests together by selecting them and clicking "Merge" in the class test list.
Or, you can click on a test name to edit it, and add more questions from the standard math tests.
