As an example (to help out those less PHP-savvy, like myself), I needed to allow access to Editors as well as Administrators. I added the following code to my functions.php file:
//MAKE REDIRECTION TOOL AVAILABLE TO EDITORS
add_filter('redirection_role', 'redirection_allow_editors');
function redirection_allow_editors(){
return 'edit_pages';
}
Where edit_pages can be any editor-level capability. To allow access for different user roles, just change this capability to one that matches the desired user role.
