Like many other requests on here I want more power with Zapier to handle items Knack is still missing today, I see Zapier has added more things (https://zapier.com/blog/workflow-automation/) such as search and would really like to see Knack support this ASAP.
So then we could lookup a record based on an email and get its ID which we can then use to insert a connected record linked by that ID.
Couldn't agree more... especially with the "Actions" Delete and update... but mostly update. You could always just update the record with an "active" to get around the delete action...
