Preview Unity prefabs in project pane?

Question

The new Unity Snaps assets are really cool, yet their ease of use is heavily limited when they don't show a preview for the prefab. In the image, notice how they are all named "Deck_Wall..." in the Project pane, and all show a cube as preview, so I can't differentiate them (unless I double-click on the Prefab to see its details, and even then, when clicking back I'm again looking at dozens of same-shortened-name Prefabs).

What am I doing wrong, is there a way to see the prefabs in the project pane? Thanks!
