Updating Records with Zapier without deleting the existing data?

[Emmanuel_Saint-]

I setup a Zap to update one table from a base without date from another table. It works great but the problem is that I want the update to only add the new data to the existing one (I am updating 2 fields: attachments and a long text field). So far when I update a record, the new input deletes whatever was in that cell before. Is there a way to keep the existing data and just add the new one to it?
Thanks!

You need to fill all the fields, not just the 2 fields.

And more specifically, you need to tell Zapier to fill each field with the value that found in that field when it looked up the record. Zapier has a special menu for instructing it to find a value from the record it looked up initially, and then using that value in the creation of the new record.

@Emmanuel_Saint-Marti Were you ever able to solve this? I’m encountering the same issue: New attachments added by Zapier delete the previously existing ones in the cells.

Thanks in advance!
