How can I override an element of a partial when that partial consists of an array?

Question:
How can I override an element of a partial when that partial consists of an array?

Example:
Given the partial below, I want to override the partial’s second element (i.e. {"partial_element_2": "some content"}) when I apply that partial. Is it possible to access and override this element via an index?

// the partial
"partials": [
  {
    "id": "dummyPartial",
    "partial": [
      {"partial_element_1": "some content"},
      {"partial_element_2": "some content"},
      {"partial_element_3": "some content"},
    ]
  }
]

// elsewhere in the App where I use the above partial
"@whatever": {
  "partial": "dummyPartial",
  "override": {
      // here I want to override the second element in `dummyPartial`
    }
  }
}

Hi,

maybe something changed in the meantime, but the last time I asked for this, it was not possible to override specific parts of an array using a partial.
