So if you are on 5.4.2, you have 2 solutions :

• Upgrade your Nuxeo to 5.6 :D
• Or if you have some development skills create your operation with Nuxeo IDE.

With Nuxeo IDE it will be really quick to do that :

• I let you look the Nuxeo IDE installation documentation : http://doc.nuxeo.com/x/ZYKE

• Then you create a new Nuxeo Plugin Project (click on the yellow button > new Nuxeo Plugin name it > next > next )

• Create a new Operation (click on the yellow button > new Operation > name it > Next > Next )

• And finally you fill the operation :

  @Operation(id = YourOpertion.ID, category = Constants.CAT_SUBCHAIN_EXECUTION, label = “Run For Each”, description = ““) public class YourOpertion {

  public static final String ID = "YourOpertion";
  
  @Context
  protected OperationContext ctx;
  
  @Context
  protected AutomationService service;
  
  @Param(name = "id")
  protected String chainId;
  
  @Param(name = "list")
  protected String listName;
  
  @Param(name = "item", required = false, values = "item")
  protected String itemName = "item";
  
  @Param(name = "isolate", required = false, values = "true")
  protected boolean isolate = true;
  
  @OperationMethod
  public void run() throws Exception {
      Map<String, Object> vars = isolate ? new HashMap<String, Object>(
              ctx.getVars()) : ctx.getVars();
      OperationContext subctx = new OperationContext(ctx.getCoreSession(),
              vars);
      subctx.setInput(ctx.getInput());
      for (Object value : (Collection<?>) ctx.get(listName)) {
          subctx.put(itemName, value);
          service.run(subctx, chainId);
      }
  }
  

  }

Did you try the run for each operation with a sub operation.
