在Codeception中添加自定义请求标头

Currently there is an issue for new Safari 11.1 browser and later that regular login parameters cannot be processed in format: "http(s)://user:pass@host".

There seems to be a way for bypassing this by sending customized request header in Selenium using WebDriverBackedSelenium class.

selenium = new WebDriverBackedSelenium(driver, "http://<user>:<password>@<host>");
selenium.start("addCustomRequestHeader=true");
selenium.addCustomRequestHeader( "Authorization","Basic "+"YWRpZGFzOmFkaWRhczEyMyM=" );

Is theere a way to do this in PHP/Codeception? Since there is no WebDriverBackedSelenium class in codeception, is there some alternative to this which can be used, or some other way of doing this in efficient way?
