composer install pass command line argument or parameter to bin/console - php

Question

I'm trying to make my symfony 3.0 app capable to work with multiple kernel.
real aim : Multiple applications in one project
Generally everything is OK. I edited bin/console it's content exactly as the following. It works exactly and results what I need via php bin/console --app=api
But when I execute composer install bin/console throws the Exception naturally it doesn't knows about --app parameter. I want to make something like composer install --app=api and desired behaviour it would pass the parameter to bin/console I checked documentation and almost every pixel of the internet couldn't find a solution.
#!/usr/bin/env php
<?php
use Symfony\Bundle\FrameworkBundle\Console\Application;
use Symfony\Component\Console\Input\ArgvInput;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Debug\Debug;
// if you don't want to setup permissions the proper way, just uncomment the following PHP line
// read http://symfony.com/doc/current/book/installation.html#configuration-and-setup for more information
//umask(0000);
set_time_limit(0);
/**
* #var Composer\Autoload\ClassLoader $loader
*/
$loader = require __DIR__.'/../apps/autoload.php';
$input = new ArgvInput();
$env = $input->getParameterOption(array('--env', '-e'), getenv('SYMFONY_ENV') ?: 'dev');
$app = $input->getParameterOption(array('--app', '-a'));
$debug = getenv('SYMFONY_DEBUG') !== '0' && !$input->hasParameterOption(array('--no-debug', '')) && $env !== 'prod';
if ($debug) {
Debug::enable();
}
switch ($app) {
case 'api':
$kernel = new ApiKernel($env, $debug);
break;
case 'frontend':
$kernel = new FrontendKernel($env, $debug);
break;
default:
throw new \InvalidArgumentException("[--app|-a=<app>] app: api|frontend");
break;
}
$application = new Application($kernel);
$application->getDefinition()->addOptions([
new InputOption('--app', '-a', InputOption::VALUE_REQUIRED, 'The application to operate in.'),
]);
$application->run($input);

You can use composer install --no-scripts to prevent automatically running app/console after installation.
Or you can remove the the bin/console commands from the scripts section in your composer.json altogether, which probably makes more sense. See https://github.com/symfony/symfony-standard/blob/master/composer.json#L33-L34
Or you can use environment variables instead of arguments.
