Especially for use with the Open Data Portal, you will have files with the same data, but in different file formats (XLSX, CSV). It would be great to be able to create one item in Content, but allow multiple files to be attached. This way, as an editor, I only have to enter the description, terms of use, etc once, and as a data retriever, I can click on an entry and then choose which of the available formats I want to download.
