HubSpot customer support asked me to describe our similiar use-case scenario here. We would like to report on form submission entry data. For example, we use HubSpot forms to collect product warranty registration. If the same customer fills out the form twice the product serial number (custom property) is unique so the submissions will be almost identical except for this field. But only contact data can be displayed in a report, not form data. The report will only pull the latest value from the product serial custom property for each entry. Ideally the report could pull from the form submission data and show each entry with each serial number displayed.
