Как изменить структуру JSON с помощью Python?

Данные приходят в таком формате:

{
  "data": {
    "columns": [
      "time",
      "weight",
      "power",
      "position",
      "home",
      "wear",
      "type",
      "color",
      "year",
      "name"
    ],
    "values": [
      "2022-08-07T17:48:00",
      1,
      1,
      1,
      1,
      0,
      1,
      0,
      2016,
      665,
      "2022-08-07T17:50:00",
      2,
      2,
      2,
      2,
      2,
      2,
      0,
      2016,
      665
    ]
  }
}

Нужно получить:

{
  "data": {
    "columns": [
      "time",
      "weight",
      "power",
      "position",
      "home",
      "wear",
      "type",
      "color",
      "year",
      "name"
    ],
    "values": [
      ["2022-08-07T17:48:00",
      1,
      1,
      1,
      1,
      0,
      1,
      0,
      2016,
      665],
      ["2022-08-07T17:50:00",
      2,
      2,
      2,
      2,
      2,
      2,
      0,
      2016,
      665]
    ]
  }
}

Написал код. Но он очень долго преобразует

df_values = dt["data"]["values"]
num_row = (len(df_values))//10

for n in range(num_row):
    df_temp = df_values[:10]
    df_values = df_values[10:]
    df.append(df_temp)
