Possibility of adding an upload attachment to the moderator feedback section of this plugin?

[Athena3030]

My query is in reference to a previous query that was posted but the conversation has been locked. https://moodle.org/mod/forum/discuss.php?d=365681#p1474478

In this module, you can grade students work make comments and upload a feedback document. There is then a separate section for moderation that is hidden from students. This section allows the moderator to agree/disagree with feedback and add comments by way of a comment box.

My question is, is there anyway the option to upload a document can be added to the moderator section so that the moderator can add a feedback template that is not seen by the student?
