Swagger schema - anyone done this? non progress question

In swagger I can add a schema by doing this:

responses:
200:
description: "successful operation"
schema:
type: array
items:
$ref: '#/definitions/Organization'

That will give me the following:

[
  {
    "ClientNo": 0,
    "ClientID": "string",
    "Name": "string",
    "Address": "string",
    "PostOffice": "string",
    "Logo": "string",
    "InvoiceNo": 0,
:
:

But if I want to add {"Organizations":  in front of it, how can I do that? 

{"Organizations":[
  {
    "ClientNo": 0,
    "ClientID": "string",
    "Name": "string",
    "Address": "string",
    "PostOffice": "string",
    "Logo": "string",
    "InvoiceNo": 0,
