Prefab/Model preview rotation

Hey,

I'm building an editor and would like to leverage the Project for model management instead of having to reinvent the wheel and display them manually in the editor's Inspector.

Is it possible to:

1) Modify prefab/model/mesh previews' transforms (or camera) in the Project view?
2) Use a custom image/texture as a preview?

The default rotation is wonky at best for my use-case. I'd like to be able to see the models straight on instead.

In the simple example below, the rotation of the preview hides information which would be visible if it were straight on.
In more complex cases, the models are illegible due to the rotation.

I reposted this thread in the seemingly more approppriate Extensions subforum. Feel free to delete this, mods.
