   hi @dima-asana @feng-tao Any updates on the above comment for running backwards dag from dag definition.
   
   ```
   from airflow import DAG
   dag = DAG(
       dag_id = "...",
       scheduled_interval = "@daily",
       run_backwards = True,
       ...
   )
   ```

> Hello,
> I think there is a need to have reverse backfilling option as well because recent jobs would take precedence over the historical jobs. We can come up with some variable in the DAG such as dagrun_order_default = True/False . This would help in many use cases, in which previous date pipeline does not depends on current pipeline.
