Asset Library - Custom camera poses, materials and Windows paths

Hi. I’ve been experimenting with the asset browse library from Blender 3 alpha (August 21 download). I understand how to store locally in a windows path folder (let’s call this the GLOBAL library) and then how to store locally in the .blend file (let’s call this the EMBEDDED library). My question is: If you load your .blend file containing embeded assets in the asset browse library, how do you STORE them in the GLOBAL library (aka: the windows folder path?)

Another question: Selecting the active camera and refreshing the view, to get a new preview, does not work on Blender 3 alpha (August 21st), as mentioned here:
What other steps do I need to configure to get the preview and the material right?

Here’s a video showing the 2 questions:
