How to change Ship to address post ship confirmation

Hi Team

We have a business process where our shipment routes through different value added activity such as Installation service which typically has a lead time and is a third party site. To track this we have Multi leg trips and the status of the same tells the status of the shipment delivery.

In some instances the final delivery site is changed and logistically we are able to manage this change manually even though system has a different address such as creating a manual doc etc.. However systematically we need the right address as to track our POD as well as Tax particularly when it is a Import shipment.
