Not really the way you'd expect, or hope.

That's the problem you can't convert to N-color yet in Photoshop. Back in
the day, the OS 9 ColorSync plugins for Photoshop worked and the deceased OS
9 MonacoColor plugin for Photoshop too.

Depends A LOT upon the RIP and how you set it up.

TIA for any replies!
So what n-color setup are you thinking of doing here? Red, blue, or
Hexachrome? Gretag's new multicolor plugin for Photoshop is the obvious
first choice for the price. Pantone has been steadfastly updating their
multicolor plugin, HexWare for years. It has good soft proof support and
selective color editing too *before* separating to a multi channel doc in
Photoshop.
