Make your preferred changes > Click Save
Make this property searchable within your contacts (if you want to filter for this data point)
Show in Contact Profile (if you want this to show up on the profile's left panel for easy viewing)
Some Helpful Tips:
Provide answer options that will help you better organize and segment your customers into appropriate groups. For example: Ask what products they might own. Certain customers might be more helpful in promoting one product versus others.
