Hi I have a lengthy workflow and am trying to add a column in the input tool. Do I have to go through the entire workflow to select the new column and click select to have the column added in my final output select tool. Lately I had to add many new columns and its time taking to manually go through the workflow and click select and refresh the workflow to get the new column appear. Is there and easier way to add a column from the beginning input tool to let it appear in the output select tool. Your help will be much appreciated. Thanks
