Overwriting nested translations in I18n

Question

Say I have the following en.yml:

default_category: &default
  car:
    wheel: Wheel
    engine: Engine
    ...
    ...
    breaks: Breaks

some_other_category:
  <<: *default

What would be the best way to overwrite the word breaks without having to copy paste all the other translations?

Tried so far:

If you do this:

default_category: &default
  car:
    wheel: Wheel
    engine: Engine
    ...
    ...
    breaks: Breaks

some_other_category:
  <<: *default
  car:
    breaks: Super Breaks

All the other translations like wheel and engine are gone for some_other_category because I'am overwriting all translations for car:

If you do this:

default_category: &default
  car:
    wheel: Wheel
    engine: Engine
    ...
    ...
    breaks: Breaks

some_other_category:
  <<: *default
  car:
    wheel: Wheel
    engine: Engine
    ...
    ...
    breaks: Super Breaks

There's duplicate code due to copy/pasting.

The option to move the default pointer to the car is not really an option in my scenario.

Is there a nicer way to do this?

Answer 1

Fixed it myself, the solution is to add an extra pointer to car, not move the pointer.

default_category: &default
  car: &default_car
    wheel: Wheel
    engine: Engine
    ...
    ...
    breaks: Breaks

some_other_category:
  <<: *default
  car:
    <<: *default_car
    breaks: Super Breaks
