We actually do already cover what you’ve mentioned, it’s probably a bit hidden in some courses though. For Shader Graph I covered this about a few months ago starting here: https://cgcookie.com/lesson/creating-your-first-shader-graph and it goes into creating a few unique shaders with it.
Regarding import/export from Blender to Unity I covered that in a few courses and also through a more in-depth article. Here is the article: https://blog.cgcookie.com/importing-and-exporting-game-assets/ it goes into the process of exporting/importing from Blender to Unity and covers a variety of topics on the subject. If you have any other questions or are looking for something else let me know. Thanks!
