title: Multistage YAML pipeline to have seperate stage without dependencies
body: <p>In Azure DevOps, I am using a Multistage YAML pipeline for Build and deployment. The screenshot shows the current pipeline setup. I wish to have sandbox1 separately without dependency on Build.</p>
  <pre><code>trigger: none
  pr: none
  stages:
  - stage: 'Build'
    jobs:
    - job: 'Build'
      pool:
        vmImage: ubuntu-16.04
      steps:
      - checkout: none
      - powershell: |
          echo &quot;Hello Testing&quot;
  - stage: 'Sandbox'
    jobs:
    - job: 'Sandbox'
      pool:
        vmImage: ubuntu-16.04
      steps:
      - checkout: none
      - powershell: |
          echo &quot;Hello Testing&quot;
  - stage: 'DEV'
    jobs:
    - job: 'DEV'
      pool:
        vmImage: ubuntu-16.04
      steps:
      - checkout: none
      - powershell: |
          echo &quot;Hello Testing&quot;
  - stage: 'QA'
    dependsOn: ['DEV','DEV1']
    jobs:
    - job: 'QA'
      pool:
        vmImage: ubuntu-16.04
      steps:
      - checkout: none
      - powershell: |
          echo &quot;Hello Testing&quot;
  - stage: 'PROD'
    jobs:

  - stage: 'sandbox1'
    dependsOn: 'Build'
    jobs:
    - job: 'DEV1'
      pool:
        vmImage: ubuntu-16.04
      steps:

      - checkout: none
