You might try using the Picture Controls, page 108 in the D90 manual. It lets you alter the setting for the different modes and save them to a specific file, which you can then load into the camera and onto your memory card. If you have a copy of Thom Hogan's D90 eBook take a look starting on page 330. This might be of help.
