Explanation
The consultant should design a solution using an OmniScript with multiple Step elements to meet the requirements. An OmniScript is a tool that can design customer interactions using elements and actions. The consultant can use an OmniScript to display client information, profile attributes, and investment instrument information. A Step element can group related fields and elements in an OmniScript, and display them in a page or a section. The consultant can use multiple Step elements to organize the information into logical groups, such as client information, profile attributes, and investment instruments

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.
