Hi Burr - no for now at least it won't be able to be set on a per-object basis, it's a global setting that controls everything in the viewports.

Maybe in the future it can get set by style, but that could possibly have some performance difficulties.

I'm kind of getting an idea of where this will go in the UI, probably there will be some stuff in Options / View to control the default light setup, I should be digging into that pretty soon here.
