Welcome to the community @cobalt700!
After much wait, we just released this new feature to update records to Airtable 
.
We announced it on our last release notes: 🆕 [July] Monthly Update on Bardeen: Airtable commands, scraper model suggestions, new use-cases and many fixes! - Version 2.27
We’ll work on documentation on how to use it.
Yet in the meantime, it behaves the same as the Google Sheet update command, which @Deyan_Petrov generously created a tutorial here: How to use Update Google Sheet rows
PS: Remember to post your questions on 
Help and questions instead of 
Getting started . Moving it that way
