I have more than a few facilitators asking for dotted or dashed strokes (borders) on shapes.
Following up here @Nate . Happy to report there has been some progress made on shape border styles in the most recent release - another step toward improvement 
You can now change the border style on shapes and adjust the border’s thickness ! We hope this helps when creating architecture diagramming and other workflows.
Try it out and let us know what you think
