Review Data Reporting

Would be nice to have better reports for reviews, for example:
1. A CSV or Excel file dump of all comments in a review showing all details associated with the comments. The current CSV file has the history but not all fields (like defects and associated data).
2. A report with defect rate for a review. Lists all the defects, can be categorized by type. Also would be nice if you could do this by project and across projects
3. Time report to show the amount of time by person and total of a review. This should also be capable of doing it by project (for all reviews) and by all reviews.
4. Review Summary report that shows items 2 and 3 in a summary format and can be done for project and all reviews.
