Supervisor comments
This feature allows the supervisor approval process to be done based on comments for each uploaded file. When uploading a file users will be able to write a message informing about the upload reason. After reviewing the file and the message(s), supervisors will be better able to choose between approving or revoking the file. They will also be able to write messages indicating why a certain action was taken.
Supervisor comments flow
When uploading a file the user can specify why the supervisor should approve it or why the file is needed.

After the user has uploaded a file without specifying a reason, there is an opportunity to add one later while the file status is pending approval.

In the Pending Approval page the supervisor will be able to view the messages in the Reason column.

By clicking on the more actions button and then on the Supervisor Approval action, a modal will open that will display all the information regarding the approval process on the selected file.

Please note that supervisors will be able to leave comments when approving and revoking files, but they can also just leave simple messages without changing the state of the file by choosing the Message only option.
