How to separate staging logs from production logs (Heroku)?

I have at least two environments on Heroku: staging and production. Is there a way to separate staging logs from production logs under the same account? Or do we need to set up two accounts? Do I need to register separate drains?

The doc says we can use tags. But our team does not want to co-mingle logs. Does New Relic have any suggestions?

If that won’t work for you then you’ll need to either use tags or different accounts.
