As a companion to my other suggestion (https://forums.autodesk.com/t5/ideastation-request-a-feature-or/change-sketch-line-type/idi-p/704663...)....
Solidworks has a useful sketch feature: "Fully Define Sketch". This automatically creates sketch dimensions and constraints to fully define a sketch. It can often be a real time-saver, and would be a really nice add-on for Fusion, especially when importing sketches from other CAD systems.
