26C Help Desk Satisfaction Survey: Required Fields

Is making certain questions required supported in the Help Desk survey? (Send employee satisfaction surveys after a Help Desk request is resolved)

I have configured this via the Survey Authoring Agent Team and asked it to make question 2 required. The response it gave was that it had done so, but in reality all it had actually done was append "(Required)" to the label. The screenshot below shows that was able to submit without entering anything in question 2.
