The consultant can recommend creating a reusable OmniScript to update address information. A reusable OmniScript is an OmniScript that can be embedded in another OmniScript as a sub-process. This way, the consultant can create one OmniScript that collects the address information in a consistent way using the same labels and input elements, and then use it in multiple OmniScripts that need to update address information. This will improve the design and maintenance of the OmniScripts.
