Checklist due dates are set to effective X weeks from date transaction was performed

Summary:

Got a question, noticed that effective due dates that appear on checklist items requiring action (eg. by separating employee) appear with a date 2 weeks from the data the termination transaction was processed in HCM. Is there a way to change this so checklist items completion due date are 3 days before the actual termination date (or last day worked)?

Content (required):

Same goes for onboarding and offboarding items (we are yet to implement Journeys so these are purely checklist items) having onboarding items completion due date set X days/week before the new employee commencement date, and offboarding item completion due dates set to X days/weeks before the employee's last day of employment. Currently dont see this as an option and the current configuration doesnt really make sense
