Registering composition tokens in Plasmic

I can register single tokens, but is there any way to register composition tokens like these layouts: ?

I can then have one token that applies multiple values. In Figma that would mean I can apply a layout token to an auto layout, so I’m hoping to do this in Plasmic

Composition tokens are like this in Token Studio. But I’m not expecting to register this json directly as it goes through a transform.

{
  "composition": {
    "1": {
      "value": {
        "verticalPadding": "38",
        "horizontalPadding": "40",
        "itemSpacing": "24"
      },
      "type": "composition"
    },
    "2": {
      "value": {
        "verticalPadding": "60",
        "horizontalPadding": "80",
        "itemSpacing": "40"
      },
      "type": "composition"
    }
  }
}
