You can open one of the images in a folder, apply the settings you want to that image in the standard RPP interface, and then apply those settings automatically as the default settings for the folder using CMD-D (or clicking on the “D” button in the upper right cluster of buttons). If you CTRL-Click on the “D” button you will specify a fixed WB (versus AUTO).
You can also use the history panel to specify the particular settings for that directory.
Once the settings for the directory are specified, all images in that folder will be processed with those settings.
