I fond a smal hack to get this function working.
1. In the database, Add a column in wp_wce_editor_content table, call it ‘args’
2. In the php file custom-css-js-php.php, Find the line:
$wp_func_name( $hook->tag_name, $func_name , 10 , $hook->accept_args );
replace with:
$wp_func_name( $hook->tag_name, $func_name , $hook->args , $hook->accept_args );
3. Now you can manuly insert extra arguments in the database column after you have created your code, use comas to seperate your arguments.
