Hi Susan,
I'm a former customer (Creative PM), now an Adobe Workfront employee. We used the descriptive text field to link to the creative brief in our digital asset manager. I just tested adding a word doc to documents in a project. I was able to right click on the document name and "copy link address" to the document. When I paste into the browser, that appears to download the file, so I think that could work too but I'd test with another user to make sure there aren't any hiccups with your particular setup, permissions, or file type. 😊
