How to enforce unique answers with SharePoint survey’s Rating-Scale questions?

SharePoint surveys support various types of questions, one of them is the Rating-Scale question type which is used to collect users’ ratings.

Let’s say we want to get employees’ opinion about the upcoming company event, and learn which activities are most preferred. In this case the following survey might do the work:

In this case, users may also give different activities the same rating.
For example: in the following survey the user likes "Spa" and "Cooking class" in the same level so he gave them the same rating:

However, there are other scenarios which require unique answers, or unique ratings. In these cases we would like to prevent users from giving the same rating to several answers.
The problem is that SharePoint does not support that, so you cannot enforce unique ratings in Rating-scale questions.
To answer this business challenge, we at KWizCom have added a feature to KWizCom’s Survey Plus web part, which enables enforcing unique answers in rating-scale questions.
When using this new feature, end-users will not be able to provide the same rating for different options; when an end-user rates an option in the rating-scale question, this rating becomes disabled (grayed) for all other options as you can see in the following screenshot:
So, as you can see in this example, after a user rated "Cooking class" as 5 he can rate other options between 1 and 4, but not 5.
You can check-out this new feature by downloading a trail version of the Survey Plus web part, please feel free to give us your feedback!
