MANAGER BASE PATH

I have recently found a lot of SQL Inject Attempts on my site with people trying to hack the Manager/Index.php file.

In future versions, please all the BASE PATH to the Manager to be a variable as well.
define(’MODX_USERDEFINED_MANAGER_PATH’, ’SECRETFOLDER’);

if (!defined(’MODX_MANAGER_PATH’)) define(’MODX_MANAGER_PATH’, $base_path.’manager/’);
if (!defined(’MODX_MANAGER_URL’)) define(’MODX_MANAGER_URL’, $site_url.’manager/’);

if (!defined(’MODX_MANAGER_PATH’)) define(’MODX_MANAGER_PATH’, $base_path.MODX_USERDEFINED_MANAGER_PATH);
if (!defined(’MODX_MANAGER_URL’)) define(’MODX_MANAGER_URL’, $site_url.MODX_USERDEFINED_MANAGER_PATH’);

Evo? Revo?
By what did you find this, so I can check my sites too.
