Hi Jeremy,
You can get a file to download with a pre-assigned filename if it’s a PDF. It is a bit of a faff though. I have to save the Word doc as a PDF, open it in Acrobat, open the document properties and add the filename I want in the document name property field. After that it’ll open in browser and download with my chosen file name.
Have a look at the Team Vision sheet in topic 2 of this course: https://juvolearningsolutions.evolveauthoring.com/courses/5ef45fb220dcc2481c48a361/preview/index.html?isShared=true
