GitHub user hnomichith added a comment to the discussion: Add the ability to 
backfill a DAG based on past Asset Events

Thanks for your answer.

Given your answer, I'm not 100% sure we understood each other: the UX to 
"backfill" this DAG could be exactly the same as the one currently existing. 
It's just that currently, when you try to backfill a DAG triggered on Asset 
events, you select a time period, and it always shows "No runs matching 
selected criteria", independently of the events on which it would have reacted 
if it was already created and unpaused.

The script (if you refer to it how I describe it) still has the caveat of 
running all downstream DAGs, and technically creating new events while 
conceptually the Asset has not been touched. It's a solution, but not really 
the most flexible IMO. If the POST `/api/v2/dags/:dag_id/assets/queuedEvents` 
was available, here indeed a script could do anything.

What do you think? Was there a mis-understanding?
