Is it possible to limit array lengths in Studio?

Hi all!

I'm getting my feet wet in mocking with importing OpenAPI docs from our services into Studio. So far so good, but I noticed that the dynamic mocks generates a high amount of elements in array types. I have tried various faker options to limit those amounts, but to no avail.

How should I limit the amount of items an array generates?

For example:

 HotspotImage:
      type: object
      properties:
        url:
          type: string
          format: uri
          x-faker: image.imageUrl
        title:
          type: string
        hotspots:
          type: array
          items:
            $ref: '#/components/schemas/Hotspot'
          x-faker:
            datatype.array:
              min: 1
              max: 3
      required:
        - hotspots
        - title
        - url

As you can se above I have attempted to limit the hotspots array to be random between 1 and 3, but without luck, they simply become empty instead of limited. It still generates about 15 items.
