Hi,
In my pipeline, i am copying files from one blob to another blob, but i have to add two new columns into the new blob file. This will be a daily activity with 5 daily files. So, For Each childitems (i.e file within the source blob container), copy them to the sink (new blob container), but add the filename and current UTC date to each file as new columns. I am able to achieve this if i dont have a ForEach and have a fixed source. But , when i click on the "Additional Columns" in the source i get the below 
Any ideas on how to circumvent this and add two new columns dynamically.
