We generally perform code reviews when an issue is resolved rather than on every single commit.
Is there any good way to do something similar to the old way in crucible where you could perform code reviews on the full source or on diffs across multiple commits?
The best way I can see is to create a "code review" branch from an old commit of the branch you were working on and then manually perform a commit of the latest version of the code to the "code review" branch. Of course this is somewhat laborious so if there is a simpler/easier process I am very interested.
