Is it possible to use github webhooks whitelist IP in this way?

- id: xxxx
  execute-command: "xxx"
  command-working-directory: "xxxxxxxx"
  response-message: Executing deploy script
  trigger-rule:
    and:
    - match:
        type: ip-whitelist
        ip-range: readFile "github_webhooks_ip_list.txt"
    - match:
        type: payload-hmac-sha1
        secret: xxxxxxxx
        parameter:
          source: header
          name: X-Hub-Signature
    - match:
        type: value
        value: refs/heads/xxxxx
        parameter:
          source: payload
          name: ref

That's not currently possible. We would need to define a readFile template function. We currently only support a getenv function (see docs).
