Add data column activity in Studio X

I am extracting a datatable from a website and need to add additional info to the datatable but I couldnt find Add Data column activity in Studio X, is there any alternative way to add data column to a data table.

You can consider the new column as another datatable and do a merge or join the datatables as per your requirement. You will be able to see these activities if you turn on the developer filter in activities panel in studioX.
