Triggering Tasks in a Journey based on action reason

Summary:

Is there a way to trigger tasks based on the date of first action reason rather than the date of the previous task?

Content (required):

We're creating an induction journey for our teams and need the ability to have tasks trigger from the person's start date. EG one week from start date - task 1, one month from start date - task 2. We can only find a way to trigger task two based on the date task one was completed? Is this the correct functionality?
