title: Jenkins Workflow: How to get or set step id
body: <p>We would like to reference a step inside a parallel task of a Jenkins workflow. But it seems that step IDs are created non deterministic for steps in multiple parallel tasks. For a input step it is possible to manually specify the step id. Is it either possible to specify a step id for a shell step or query the step id?</p>
  
  <p>The purpose is that we would like to create a link to a shell script inside a parallel task.</p>
