Create custom Core/Record.php

[dangerdodis]

I want to edit Record.php. But I do not want to do this on my own. I created it specially but it does not work.
It works for the controller. But it does not work for the core/controllers folder.
The sample namespace code is below.

namespace Espo\Custom\Core\Controllers;
use \Espo\Core\Exceptions\Error;
use \Espo\Core\Exceptions\Forbidden;
use \Espo\Core\Exceptions\NotFound;
use \Espo\Core\Exceptions\BadRequest;
use \Espo\Core\Utils\Util;
class Record extends Base
{
const MAX_SIZE_LIMIT = 200;
public static $defaultAction = 'list';

You can not override core controllers in upgrade safe way, only each controller separately.
