author id

Need to display a document download url and the author as well

I am using Bonita Subscription 7.1.2 .
I have a task where multiple approvers will review a task and attach a document each.
The requestor will be able to see the final status after all review is complete.
The requestor should be able to see the documents that the approvers have attached.
I was able to do that , but currently there is a list of all document url/links available.
To make more sense out of it, I need to display the approver name beside the document so that the requestor is able to identify which approver has attached which document.
