Yes. As of 1.1
The quick explanation is you need to provide an array of incorrect
values to the <numericalresponse> throught the 'incorrect' attribute.
You need to provide at least as many incorrects as 1 less then the
number of bubbles on the exam. You can provide more if you want to.
(in Edit mode there should be an 'Incorrect Answers:' field you can
Minimal example problem:
Correct answer is 1. <br />
<numericalresponse answer="$answer" incorrect="@incorrects">
Let me know if any this fails to work for you.
