Skybox Reflections in Preview

Not sure if this is a bug, or not implemented, or I'm blind, but essentially can we get skybox reflections in the preview when working with PBL shaders?

Everything I crank up the metallic value, the object just goes dark. Would be nice if we can actually get some reflection preview in Shader Forge then having to get into Scene window, add reflection probe, and go back and forth .

Sincerely,

Jason
