Use case:
We are loading Gainsight PX Users to the Gainsight CS People/Company People/Relationship People objects. Our users do not always have their first name and last name set in their profile, so these fiels might be NULL/empty in Gainsight PX. If the person already exists in Gainsight CS, their first/last name will be overwritten by the Upsert (which we need as we are also populating username and usage metrics).
Idea:
Provide an option to not overwrite fields when they would be overwritten with NULL or empty values.
