    Hi,
    Martin is right.  You may also want to give Pivot in Turbo Prep a try: https://academy.rapidminer.com/learn/video/turbo-prep-data-pivoting

    I now use Turbo Prep every time I need to pivot:

    1. Scott loads data file
    2. Scott does his usual ETL nonsense and realizes he needs to pivot
    3. Scott right-clicks on the output port and jumps to Turbo Prep



    4. Scott drag-and-drops stuff inside TP's pivot tool until he gets what he wants
    5. Scott inserts thing back in to my process and keeps on truckin'.

    That right-click TP jump is life-changing for an ETL geek like myself.
