CKEditor: how to define custom configuration file?

[Connie]

I want to create a custom file, which will not be overwritten by updates.
The standard configuration file is per default admin/template/js/ckeditor/config.js

CKEDITOR.config.customConfig defines the URL Path to the config-file, which is per default '<CKEditor folder>/config.js'

see here: http://docs.cksource.com/ckeditor_api/sy...stomConfig

I tried to set in gsconfig.php:

Code:

# WYSIWYG Editor Options
define('GSEDITOROPTIONS', "
  enterMode: CKEDITOR.ENTER_P,
customConfig : 'admin/template/js/my.js'  
");

or

Code:

# WYSIWYG Editor Options
define('GSEDITOROPTIONS', "
  enterMode: CKEDITOR.ENTER_P,
customConfig : '/my.js'  
");

or

Code:

# WYSIWYG Editor Options
define('GSEDITOROPTIONS', "
  enterMode: CKEDITOR.ENTER_P,
customConfig : /my.js'  
");

it all does not work. So I see only the chance to edit config.js which comes with getsimple, but I would like to have another, customdefined configuration
