Merge $psr4 array

Hello,
I am trying to merge additional routes from an external file with the $psr4 array. Is this possible?
Thank you

This is how CodeIgniter loads its files from system/bootstrap.php

PHP Code:

// system/bootstrap.php

// Setup Framework Paths.
APPPATH
ROOTPATH
SYSTEMPATH
WRITEPATH
TESTPATH

// Load Constants and Common Files.
APPPATH    . 'Config/Constants.php';
APPPATH    . 'Common.php';
SYSTEMPATH . 'Common.php';

// Load Autoloader and Modules.
SYSTEMPATH . 'Config/AutoloadConfig.php';
APPPATH    . 'Config/Autoload.php';
SYSTEMPATH . 'Modules/Modules.php';
APPPATH    . 'Config/Modules.php';

// Load Services.
SYSTEMPATH . 'Autoloader/Autoloader.php';
SYSTEMPATH . 'Config/BaseService.php';
SYSTEMPATH . 'Config/Services.php';
APPPATH    . 'Config/Services.php'; 


You might be able to extend the system/Autoloader/FileLocator.php and array_merge youtr file in there.
