Pipeline combination operation

Can Steps in a Stage of a Pipeline Be Dependent? For example, there are step A, step B, step C, and step D in a stage. B and C depend on A. That is, B and C can be run only after A is run. B and C run at the same time, and D can only be run after C is finished. Is there any way to do that?

by default steps in a stage of a pipeline are executed sequentially
you need to use the parallel step if you want to run something in parallel.
See this simple pipeline

node() {
    sh 'echo step A'
    parallel stepB: {
        sh '''
          echo stepB
          sleep 2
          echo stepB
          sleep 2
          echo stepB
        '''
    },
    stepC: {
        sh '''
          echo stepC
          sleep 1
          echo stepC
          sleep 1
          echo stepC
        '''
        
    }
    sh 'echo stepD'
}

What if the dependencies between steps are complex?
