Probably related here, but I see that Dotenv supports passing in a file name.
My situation is that I've got a /var/www that contains directories for different sites. If I want to store multiple .env files, one for each site, above the public roots, I'll obviously need different filenames. Being able to pass through the file name as the second arg in the $env = WCM\WPStarter\Helpers::settings(__DIR__); call would be handy.
