Did you try it?

Without ForceArray => [qw( type )]:

$VAR1 = {
          'type' => {
                    'scenario1' => {
                                   'report' => 'Dummy2'
                                 },
                    'default' => {
                                 'report' => 'Dummy1'
                               }
                  }
        };


$VAR1 = {
          'type' => {
                    'report' => 'Dummy1',
                    'name' => 'default'
                  }
        };
