When creating document mapping sheets for Projects, or Functional and Non-Functional Requirements response sheets for RFPs, it would be greatly helpful to be able to attach a single file to Multiple Rows in a Sheet. Now, we can only upload a file to a single row, but if that one file applies to multiple rows, it would have to be uploaded multiple times to each row it applied to. This can and will become a management nightmare as some documents are fluid and will require updating or versioning after upload. This means that the user would need to reupload a single updated file to multiple rows with every update. If we could attach a file to multiple rows, this would solve this problem completely.
It would be even better if when you upload the document to multiple rows and update one, and have it apply to all.
