Airtable and Baserow pieces : we can't filter fields to fill or update

The problem, whether in Airtable or Baserow pieces, is that it is not possible to filter the fields to be filled in or updated. You end up sending NULLs in the irrelevant fields of the table, which requires extreme contortions and leads to errors in the flow.

It is absolutely FUNDAMENTAL to be able to filter the fields you want to work on when creating or updating a row. Fields not affected by our flow should not receive any information.
