Copying attachments from Feed to an object's attachments section

We are trying to copy all attachments posted in an object's feed to the attachment's section of the object in Freedom UI. 

Here's the scenario, we created a section to hold data about all our subcontractors. The users are leaving comments and docs in the Feed, but we want all those same docs to copy over to the record within the attachments section. 

I have used the file transfer function the business processes but the feed not your typical object.
