I've built and my team uses plannotator [1] for specs and code review. It stores all human annotated feedback, which we compile from time-to-time and iterate on coding standard skills for automated review (that seems to get better with the more feedback we provide).
You could write a script that does the same for your PR review comments, which it sounds like you maybe do with a bit more structure.
