Add Airtable List Option to return empty fields

I discovered this problem while trying to solve another problem

https://community.n8n.io/t/add-airtable-append-option-to-automatically-remove-unmatched-fields/10533/4

It is currently impossible to list an Airtable record to retrieve column names as only fields with values are returned - this causes a problem when all fields are necessary to ensure that appended data does not send any fields that don’t exist in Airtable (and avoid an error)

Below are some screenshots showing the issue
