Preferences folder link from lower blender version to upper

I have blender 2.90 Portable as main working build. I have plugins installed at 1.6 gigabytes. I want to test upper testing build which is 2.90.1 with all plugins from 2.90 addon folder. When I open blender 2.90.1 in a pop-up window, I am prompted to import all settings from blender 2.90 and it will clone into 2.90.1 preferences folder all that is needed. I would like two options. clone or link. I tried to make inner preferences folder as links and copy them into 2.90.1 preferences folder and after started blender 2.90.1 and this method doesn’t working.
