If a checkbox is clicked on a form, can a field populate from previous data?



I have a form where the user would enter a Contact 1 name and Contact 1 email. Then a bit later there are fields for Person A name and Person A email. Often Contact 1 and Person A would be the same information (but not always).

Currently in an Acrobat form, there's an option for "Person A (check box if same as Contact 1)" then Person A's name and email autofill. Is there a way to do the same thing on the Smartsheet form? Logic seems to only work for hiding and showing fields.
