Can you change the order of Onboarding notification emails?

Right now when tasks get assigned for Journeys, they all get emailed/notified at the same time. For example, if a Journey has 6 tasks, the user gets 6 emails all at the same time. Is there a way to combine them all into one email or change the timing of the emails/notifications? This gets confusing for new hires when they get a bunch of communications at the same time.
