Currently my team and I tie all reviews for a given product version together by starting the review title with the version number (i.e. 1.4.0 - Enhancing Clients Screen). This lets us find all reviews associated with version 1.4.0 by typing "1.4.0" in the Filter box on the Code Review Board, but it's very limited. If 4 items come back, and we select one, we can see the review, but none of the comments, as the comments don't contain the text "1.4.0". So to review the comments, we have to clear the filter. Now if we click the back arrow, we have to filter by 1.4.0 again to look at the other reviews under this version.

We would really like the ability to have a way to group reviews so we can get away with putting product versions in the titles, as well as being able to quickly scan through all reviews associated with a particular product version within a project.
