Visual Studio Code – Periodic cursor in VSCode

Question

I know multiple cursor is a thing in VSCode, but is there a single action (keyboard shortcut or a command) to place a new cursor every N lines in the whole file, based on initial cursor location?

Or as an alternative good-enough solution, is there a way to generate X new cursors N lines after the current one?

Context

The use case behind this question is as follow:

Imagine you have a very large json file with repeating blocks in it, the content of each blocks has the same number of lines but a very high text variability on each line.

I would like to be able to multi select all blocks using the way above, and batch-copy them to another file with a similar structure this way.

Example

{
  "main_block": {
    "name": "TEST NAME",
    "version": "1.0"
    "data_list": [
      {
        "label": "Item Name 1",
        "obj_id": "ID1111111",
        "obj_type": "TypeA",
        "properties": [
          {
            "name": "param1",
            "size": 0,
            "value": "test_value1"
          },
          {
            "name": "param2",
            "size": 10,
            "value": "test_value2"
          }
        ]
      },
      ...
      {
        "label": "Item Name 9",
        "obj_id": "ID9999999",
        "obj_type": "TypeB",
        "properties": [
          {
            "name": "param42",
            "size": 42,
            "value": "test_value42"
          },
          {
            "name": "param57",
            "size": 0,
            "value": "test_value57"
          }
        ]
      }
    ]
  }
}

Reformulating context with the example above:

• The number of lines of each object inside data_list is guaranteed to be the same (17 lines).
• In order to be able to select the first object inside each properties array through the whole file, I am looking for a way to place a cursor every 17th lines.
