ticket accept auotmation in service now

I’m researching on how we can automate ticket acceptance in servicenow.

Scenario:-
For example if there is an outage and getting 1k+ tickets opened in servicenow and team is not able accept the tickets in servicenow within the SLA.

I need some opinion on how we can we automate this .For a specific assignment group if they are getting 10 – 100 tickets at the same time , the ticket should automatically and accept and send a notification to the assign and the entire members in the team that these tickets has been automatically accepted.

looking for suggestions and opinion on this…….
