Stack two datasets

How can I stack two datasets without matching on field names ? The append action cannot be used because it matches on columns or it appends it as columns but I want to stack two dataset that have the same sorting order and I do not want to match on fields because fieldnames are different.

You will need to rename columns in both datasets to the same names, append, then rename back the resulting dataset.

See the example below.

Thanks. Could this feature be added to the merge transformation ?

Not at this point.
