Shape Map, dynamic update of TopoJSON data

The current shape map requires a static TopoJSON file to be uploaded to the visual in Power BI Desktop. We would like a way to provide the file through the data model, so that data refreshes will always grab the latest map layout.

At our company we have our custom maps fully automated, but today it is a very manual process to update the Power BI reports and re-publish them to the service. This creates the danger of us having out of date maps and not knowing about it.

We see the value of a static map, for people who don't have spaces that change often. But for us we need a dynamic alternative.

(The problem for us is made even worse since we have to include the description for a polygon as part of the key, because the shape map doesn't yet support additional fields in the tooltips. But our description data changes frequently, so we are constantly doing manual changes to any of our reports with shape maps.)
