We’re always happy to discuss adding new outlets/APIs to make customization easier. If you’ve exhausted all other options, you may need to resort to template overrides. This technique allows you to override the entire template of any Ember Component or Route f…

And then, just sharing some links/notes for others that might be in the same boat:
