Inspector: Autorotate prefab

Is it possible make the current selected prefab's preview in the inspector window autorotate around?

At the moment say I want to select one of 20 axe weapon prefabs but not sure of which one, I have to select prefab then move over to the inspector window and then drag prefab around to view it from various angles, then move back to the list, select another etc.
Sure its not a major point it takes ~5 seconds, but when you're doing it 20 times its a bit annoying, I'ld prefer to just select the first and then cycle through them with the down arrow key

EDIT: On a related note, how to change the background of that preview window from grey, eg I want to take a screenshot of the prefab, and then delete the background, the problem though with grey is if I select by color == grey, it selects some of the prefab, if I change it to eg florescent pink, I can assume only the background is selected
