title: Run specific jobs in gitlab scheduled pipeline
body: <p>I have composed a gitlab-ci.yml file consisting of multiple gitlab jobs and stages. Some jobs run on specific git branches when code is merged to that branch and some jobs are scheduled.</p>
  <p>I want to create a scheduled CI/CD pipeline in Gitlab which only contains specific scheduled jobs and not all the scheduled jobs. Is that possible?</p>
  <p>For Example this is my gitlab-ci.yml file.</p>
  <pre><code>stages:
    build
    test
    deploy
    scheduled-test-1
    scheduled-test-2
    scheduled-test-3
  
  build:
    script:
    - echo $Service_Version
    only:
    - develop
    except:
    - schedules
  
  test:
    script:
    - echo $Service_Version
    only:
    - develop
    except:
    - schedules
  
  deploy:
    script:
    - echo $Service_Version
    only:
    - develop
    except:
    - schedules
  
  scheduled-test-1:
    script:
    - echo $Service_Version
    only:
    - schedules
  
  scheduled-test-2:
    script:
    - echo $Service_Version
    only:
    - schedules
  
  scheduled-test-3:
    script:
    - echo $Service_Version
    only:
    - schedules
  </code></pre>
  <p>Now, when I create a schedule then all the three schedule tests are seen on the pipeline. I want to create three schedules which has scheduled-test-1, scheduled-test-2 and scheduled-test-3 separately. How is that possible?</p>
