If a start date changes, is there to update journey new hire to reload it on the new start date?

Summary:

If we get a new hire start date, we have journeys that trigger on the start date, but it sits as deferred on the record until the start date is reached. If the start date is changed - how can we refresh the journey to activate on on the new right start date.

We have a number of use cases where a start date may change to be earlier or later based on visa or references, but as the journey has been triggered for preboarding and onboarding, and the journey wont reflect the new date. How can we fix this. Do we have that functionality yet?
