Apologies, I think I may have not explained my point too well. If you look at the below example, currently when you want to assign a rating to a review in GARS you have to use the drop down boxes as shown below:

What I was proposing was merely to replace these drop down boxes with a simple AJAX based star rating system (it doesn't need to be stars of course, it could be the same numbering as now) . I think it would help to enhance the user experience when submitting new reviews. Please see the below rough example (apologies, I was using MS Paint
):
