@jeffv - in my example the 1 and 1(a) is basically telling Alteryx to take the user selected field from the main workflow, and update value row 1 and value a in the first column.
In other to pass additional columns into your macro, you have to bring in another control parameter, which passes data to a different action tool, which in-turn updates a different column in your text input. In the image below, I take Year from main workflow, and modify the action tool to update row1 and value 2020 in column 2.
I have also attached a modified workflow. Hope this helps.
