The history form is sent to each person and says something like "Hello Jill, please fill out this form." If her husband Frank fill out the form instead the system should not change her name and DOB to match what he submitted. This should be flagged for review.
We have had this happen multiple times now. A name or DOB change should not happen automatically. It's not feasible for every family, especially with children, to have individual phone numbers to contact.
This issue changes our system so that we no longer have "Jill" in the system and instead have 2 "Frank" profiles.
