How to pass all parent variables to a called process

ound an answer, thought I'd post for others to use. In the called process, define a start event listener that looks up the super execution and pulls all the variables local. Very handy and easy.
public class WorkflowVariableInjectorListener implements ExecutionListener {
  private static final long serialVersionUID = 1L;
   
  static Logger logger = Logger.getLogger(WorkflowVariableInjectorListener.class);
   
  @Override
  public void notify(DelegateExecution execution) throws Exception {
    logger.info("In notify");
    if (execution instanceof ExecutionEntity) {
      ExecutionEntity executionEntity = (ExecutionEntity) execution;
      ExecutionEntity parentEntity = executionEntity.getSuperExecution();
      if (parentEntity != null) {
        // Copy all the variables into me
        executionEntity.setVariables(parentEntity.getVariables());
      }
    }
   
  }
   
}
