Can you preprocess a specific region in template.php? In your template.php file, I know you can use theme_preprocess_region and check what "region" you are in, and accomplish what I am attempting like that...but I was wondering if you can do something like theme_preprocess_region_specific_region to further break things up and not have a lengthy preprocess_region function?  I can't seem to find any documentation on that.
Well, you can define your own preprocess function if you want to, since you have all the elements for that. In the theme_preprocess_region function, you can simple do :

$function = 'yourtheme_preprocess_region_'.$variables['region'];
if (function_exists($function)) {
  $function($variables);
}


Then, you just have to define the a function for your region :

function yourtheme_preprocess_region_YOURREGION(&amp;$variables) {

}
