Is there a way to display a list of all custom step-definitions in terminal?

I'm struggling to find a way of displaying all custom step-definitions in terminal in the same way the "behat -dl" does this for MinkContext and its pre-defined steps. Is there some kind of a way to make all custom-declared steps to be be displayed as well? Here's how my FeatureContext.php header looks like so you'd get a better view of the way my steps are being stored.

MyCustomContext.php:

use Behat\Behat\Context\CustomSnippetAcceptingContext;
use Drupal\DrupalExtension\Context\MinkContext as MinkContext;

class MyCustomContext extends MinkContext implements CustomSnippetAcceptingContext
