Different environment per Behat context (Symfony 4.x) - php

Question

I want to create a lot of Behat features with simulating different configurations (from yaml,xml,php files).
Official extension for support Symfony 4 - Symfony2Extension have support for configuring a different environment like:
default:
# ...
extensions:
Behat\Symfony2Extension:
kernel:
class: App\Kernel
bootstrap: config/bootstrap.php
env: custom_env
But, this extension is loaded before any suites or context. I should initial Kernel for each separate context with different config files via env.
Like:
default:
suites:
default:
contexts:
params:
env: custom_env
- FeatureContext:
or
default:
suites:
default:
contexts:
- FeatureContext:
env: custom_env
And I'll load Kernel manually inside Context.
Any idea here?

I guess you could define different profiles for each env:
default:
# ...
extensions:
Behat\Symfony2Extension:
kernel:
class: App\Kernel
bootstrap: config/bootstrap.php
php_profile:
# ...
extensions:
Behat\Symfony2Extension:
kernel:
env: prod
yaml_profile:
# ...
extensions:
Behat\Symfony2Extension:
kernel:
env: dev
