MenuTrails individual Permissions

Hi,

A certain Role must be able to have access to just one module: http://drupal.org/project/menutrails which I installed.
The Menu Trails configuration page is found under the Site-Configuration menu.

If i grant access to "administer site-configuration" under module system, the Role gets access to menu trails. But also the Role can edit every module and some other stuff which I don't want!! The Role must only have access to menu trails and nothing else from the Site-Configuration menu.

Is it possible to add administer permissions for this module?

Thanks in advance,

Aeroniro
