SonataAdmin: add new role from route defined in admin class

I need to create a new ROLE called STATUS to appear in ROLE MANAGER of User CRUD like the image at link see image, this roles is based on a custom route defined in the admin class, and a custom controller.

I've resolved modifying the config file adding a information parameter with the default list of ROLE, but this will apply to all admin class defined in the service, and I don't want that, I want define the ROLE for a specific admin class, and also that can appear in the role manager in order to be assigned a user.

Any suggestion is welcome

Thanks for help!

These are my configurations:

config.yml

#SONATAADMINBUNDLE
sonata_admin:
security:
    handler: sonata.admin.security.handler.role
    information:
        EDIT: EDIT
        LIST: LIST
        CREATE: CREATE
        VIEW: VIEW
        DELETE: DELETE
        EXPORT: EXPORT
        OPERATOR: OPERATOR
        MASTER: MASTER
        STATUS: STATUS

AdminClass

//..
use Sonata\AdminBundle\Route\RouteCollection;

class SolicitudMantenimientoAdmin extends Admin
{
    //...
    protected function configureRoutes(RouteCollection $collection)
    {
        $collection->add('status',$this->getRouterIdParameter().'/status');
    }
}

Service

<service id="sonata.admin.solicitudmantenimiento" class="Minsal\SimBundle\Admin\SolicitudMantenimientoAdmin">
      <tag name="sonata.admin" manager_type="orm" group="Solicitud" label="Solicitud Mantenimiento" />
      <argument />
      <argument>Minsal\SimBundle\Entity\SolicitudMantenimiento</argument>
      <argument>MinsalSimBundle:SolicitudMantenimiento</argument>
</service>

Controller

use Sonata\AdminBundle\Controller\CRUDController;

class SolicitudMantenimientoController extends CRUDController {
//..
public function statusAction() {
    //... code here
    return new Response('<html><body>Test</body></html>');
}

Solution

Finally I solved the problem, I read the documentation deeper (Role Handler), I made the next changes in the follow file:

security.yml

I added a new role in the security file, in the role_hierarchy section like the follow:

security:
    role_hierarchy:
        ROLE_SONATA_SOLICITUDMANTENIMIENTO:
            - ROLE_SONATA_ADMIN_SOLICITUDMANTENIMIENTO_STATUS

When I added the new role, it appeared in the ROLE MANAGER of User CRUD, like the image at the link see image

and it works!!!...
