Timeline View: 15 minute line separators, 30 minute x-axis

I would like my x-axis to have an x-step of 30 minutes, but I want to have lines separating every 15 minutes in the view.

Is there a way to have a second scale by 30 minutes, and hide the x-axis?


Please, specify which mode do you use in Timeline view?
