We've just released a new feature in Funnel which enables you to populate custom fields by searching for a match in a table and returning the corresponding value on that particular row.
This feature can be great option for normalising and matching data if the standard "When" condition, "Then" value rules aren't sufficient.
You can learn more about how the new Inline Lookup feature works in this article.
We're still actively developing this feature so if you have any feedback or requests, it would be great if you could let us know!
We hope that this makes it easier to create the custom fields you need. If you have any questions or if you require any assistance, please contact firstname.lastname@example.org and we'll be happy to help :)
