Reviewing old assignment remarks

Hi Alex, you misunderstood. I am not asking how to re-grade assignment. I am asking where can a tutor see his own feedback once posted for assignment? Often students reply to what tutor has said in the assignment feedback and require a more detailed answer. Now if tutor cannot see what he originally posted in the first feedback to a student, he cannot get the full picture of the conversation in its whole context so how could he reply? Similar to receiving a reply to an email. If you receive a reply without your original message included, it is often impossible to understand what the person is referring to. It may be easy communicating with 2-3 people. But when you're dealing with hundreds of students then it is impossible to remember what you said in the assignment.
