Using Quick Base Action to copy file attachment

Ok so I am confused about the [Record ID# of the record with the file] part of the formula. It would need to copy a different record each time, so this doesn't seem like it would work?

Each record in the destination table would need to have a link to a corresponding record in the original table, but they will be different attachments for every record.

Is this possible? Or is the only way to do this manually in every record?
