I have created a code review and I have accumalated some comments from the reviewers.Now I have new code and I want to create a review and I want to reuse or see all the comments which were there in the previous review also.How can I do this in a crucible review.
Crucible is "The tool" for doing iterative reviews.
Depending on how you create the review, one would just update the existing review with new commits.
In the case of branch reviews this will happen even automatically by default.
After modifying the review (adding new commits) reviewers will be able to see what was added and what changes were done in response to their comments.
Not sure why you want to create a new review? Please explain your workflow.
