Sort YAML file (specific level)

[MatthiasVanMeerbeek]

I'm looking for a way to sort only the second level in a yaml file.

For example, I want to go from this (random sample yaml):

type: object
properties:
  _id:
    type: string
  name:
    type: string
  list:
    type: array
    items:
      $ref: '#/components/schemas/listItem'
  detailed:
    type: boolean
  data:
    type: array
    items:
      type: object
      properties:
        _id:
          type: string
        info:
          type: string

To this:

type: object
properties:
  _id:
    type: string
  data:
    type: array
    items:
      type: object
      properties:
        _id:
          type: string
        info:
          type: string
  detailed:
    type: boolean
  list:
    type: array
    items:
      $ref: '#/components/schemas/listItem'  
  name:
    type: string

I created this regex: (^\s\s\H.*(?:\n^\s\s\h+.*)*) which selects every second level "group", but I can't seem to make it work with the plugin in IntelliJ.
Is there a way to do this with this plugin?
