This is not bug reporting, but enhancement request.

When user tries to change billing tier, it can be done when they call query with async:

job = client.run_async_query('<random_jobID>', QUERY)
job.maximum_billing_tier = 3

but in case of client.run_sync_query. it returns query instead of job. It cannot change biling tier.
Can we add biling tier parameter in Query class?
