Magento 1.9.2 admin add street column in Customers by number of orders report

[virenpatani]

I want to add street column in admin->report->Customers by number of orders.(Magento 1.9.2)

I have tried adding join query in 'app\code\core\Mage\Reports\Model\Resource\Customer\Orders\Collection.php'

protected function _joinFields($from = '', $to = '')
{   

    $this->joinCustomerName()
        ->groupByCustomer()
        ->addOrdersCount()                 
        ->addAttributeToFilter('main_table.created_at', array('from' => $from, 'to' => $to, 'datetime' => true))
        ->join(array('p' => 'sales/order_address'), 'main_table.entity_id = p.parent_id', array(
                'street'
        ));

        return $this;
}

And in 'app\code\core\Mage\Adminhtml\Block\Report\Customer\Orders\Grid.php'

$this->addColumn('street', array(
        'header'    => $this->__('street'),
        'sortable'  => false,
        'index'     => 'street'
    ));

I am getting the main table data but not the fields I have joined.

I have tried this, any other method is always welcome. Thanks in advanced.
