Some code improvement for admin controllers

I want to propese some code improvement and even will be able to do it check and contribute to repository.

Typical admin controller action contains this lines of code:

 if (!_permissionService.Authorize(StandardPermissionProvider.ManageCategories))
                return AccessDeniedKendoGridJson();

I propose to make this check at controller/action attribute level.

     [CheckPermission(StandardPermissionProvider.ManageCategories)]

What do think ?

Thanks for the suggestion.
We can think about it as a part of a more global task about the ACL.
