I'd like to build a workflow to process an input file that has more columns every month, and have a formula that calculates the YTD average for the columns. I'm not sure if this can even be done, so am looking for ideas. There's no option to have a separate input file for each month and then merging them in Alteryx before processing.
For example, in February there will 5 columns, and I need to create 2 new columns in the workflow to calculate the YTD averages for the first 2 months of the year. Then in March, there will be 2 more columns and the YTD will be for the first 3 months. And so on.
