Editing Reviews: Rating change not allowed?

I've added two reviews to the site now.  On one of them, I totally forgot to add a rating, so what I intended to be 4/5 stars (as I say in my review text), actually shows up as 0/5 stars!
 
Why is it that we can edit the review itself, but not the rating??
 
Please fix this!

I posted this a while  back -- I wanted to see if anyone else agrees this should be fixed, or if it was maybe in the pipeline?

I'd like it to be fixed as well.  But I don't know anything about if or when it would be.
