How to change/redefine variables in nested dictionary?

[Dmitry Owl]

I have dictionary:

  test:
    a:
      name: 'somevalue'
      other: 'somevalue'
      another: 'somevalue'
    b:
      name: 'somevalue'
      other: 'somevalue'
      another: 'somevalue'

How can I change value of "name" in each dictionary during play of playbook and that this has affected on all further reference to the "test" dictionary? I want to get something like this:

  test:
    a:
      name: 'newvalue'
      other: 'somevalue'
      another: 'somevalue'
    b:
      name: 'newvalue'
      other: 'somevalue'
      another: 'somevalue'

I have tried to use "with_dict", "debug" and "combine" jinja filter but didn't get any result.

I will be grateful for any help! Thank you!
