By default, all routes with yii-2 start from the index.php file and are set with the "r = {controller} / {action}" parameter.
Is it possible to change the addressing, if the initial page is, for example: admin.php.
The task is: there should be two separate designs and a different security policy for the admin and the main part of the site, some of the actions are the same (list of hotel rooms: 1 - grid with the ability to edit, 2 - page with the ability to book rooms).
