Extend postDelayed time in Kotlin

Is it possible to extend the delay time within a postDelayed?

I have a button that starts a postDelayed handler. I want the time of de handler to be extenden when I press that button for the second time before the handler is ended. Does anyone know how to do this?

This is the code I have right now

Handler().postDelayed({
                        checkBox.setBackgroundResource(R.drawable.black_button)
                    }, 3000)
