Localize a sub field in a repeater (options)

While this works well for required option, I can’t make it work for “localize” option, any suggestion ?

  "name": "features",
  "type": "wysiwyg",
  "label": "Features",
  "options": {
    "localize": true,
    "required" true

Of course I would love not to have to make the repeater field itself “localized” but only a specific field in it.

I had the same question before. It’s not possible to localize each repeat entry. The same goes for sets.
