The main admin (or Helper Admin with permission to view "User Management") has the ability to add a family to more than one home visitor.
The family will have a primary home visitor (the home visitor selected under the child), but this feature will allow another home visitor (or provider listed as a home visitor) the ability to view the family under their list . They will be able to add contacts, screenings, etc to the family.
From the home page, click on "Home Visitor Caseload"
Click the pencil icon to view the home visitor's current caseload
To assign additional families, scroll down to the section that says "This table lists families assigned that you share with their primary home visitor" (My Additional Families).
Click the "Assign Non-Exited Families" to add a family to the home visitor list.
From here, you can search or scroll to find the family you want to assign.
Check the box to add families to home visitor's list.
Click Save at the bottom.
The family will now show under the "My Additional Families" table.
The home visitor will now see that family in the dropdown under "Additional".
