Can I obtain a certain field in the parent field?

Wow, thank you for making it open source. This is really a useful library of tools. I have encountered a problem and would like you to help me with it:

The following is my original JSON structure:

[
  {
    "date": "2025-01-16-16-20-38-126",
    "location": [
      {
        "x": 2.7391487568478716,
        "y": 4.424778761061947
      },
      {
        "x": 88.20058997050147,
        "y": 4.298356510745891
      }
    ]
  },
  {
    "date": "2025-01-16-16-20-16-469",
    "location": [
      {
        "x": 2.7391487568478716,
        "y": 4.424778761061947
      },
      {
        "x": 88.20058997050147,
        "y": 4.298356510745891
      },
      {
        "x": 28.487147071217866,
        "y": 4.804045512010114
      }
    ]
  }
]

I want to convert it into the following format:

[
  {
    "date": "2025-01-16-16-20-38-126",
    "x": 2.7391487568478716,
    "y": 4.424778761061947
  },
  {
    "date": "2025-01-16-16-20-38-126",
    "x": 88.20058997050147,
    "y": 4.298356510745891
  },
  {
    "date": "2025-01-16-16-20-16-469",
    "x": 2.7391487568478716,
    "y": 4.424778761061947
  },
  {
    "date": "2025-01-16-16-20-16-469",
    "x": 88.20058997050147,
    "y": 4.298356510745891
  },
  {
    "date": "2025-01-16-16-20-16-469",
    "x": 28.487147071217866,
    "y": 4.804045512010114
  }
]

At present, I can expand the original data structure as follows:

[
  {
    "x": 2.7391487568478716,
    "y": 4.424778761061947
  },
  {
    "x": 88.20058997050147,
    "y": 4.298356510745891
  },
  ....
]

But I have no way to include the "date" field in the "location" field. What should I do? Is there something like parent that allows me to obtain the "location" field at the upper level within the location field?

I have studied the code and found that it may not be able to perform upward queries. So I added a copy function to copy content from the outside into the target structure to solve my problem, and I have submitted a PR：#13
