Its great that reviews show you related work items once you select change sets to review, but it would be very useful to be able to start by picking a work item that has a bunch of change sets related to it, and have it pull in those revisions automatically.

This is useful in the scenario that you have several developers working on one PBI and you want to do a single code review of all their changes at the end. All you need to do is put in the PBI number and get all their revisions, currently you have to go backwards and pick all their revisions leaving the door for human error to miss change sets that are part of the PBI.
