Everytime I refresh the source schema to add new tables to my airbyte postgres&gt;snowflake job, I need to reselect all of the tables one by one from the source list. Is there a workaround for this or some feature I am missing?

Basically, I just want to add a few new tables to the replication job, without removing any of the existing one.

Not yet Lucas, there is an issue to implement this feature in the future but it not prioritize right now: <https://github.com/airbytehq/airbyte/issues/4295>
The latest version of Airbyte is easier to select multiple tables and filter group of tables, did you try that?

Yes I am on the latest version. Thanks for sharing this issue.
