No there isn't. The D200, like almost all other 35mm-derived cameras has an image proportion of 2:3 (short:long edge). An uncropped image would measure 8x12 inches. So if you know you're shooting for an 8x10 print you have to learn to back off on your framing to give yourself room to crop after the fact.
There is a company out there (whose name escapes me) that makes focusing screens with etchings on them that give you crop lines for popular print sizes like 5x7 and 8x10. If you're so inclined, try a google search for focusing screens and crop lines, cropping guides, or something similar and see what happens. They are fairly expensive if I remember correctly.
