Barcodes for Connect

I need to make a barcode out of existing data, but I also need to make a barcode out of that same data with the first two characters omitted. What is the best way to accomplish this? I know I could use html slice in the datamapper to make it so I can make the truncated barcode, but I’m trying to make 2 barcodes. Super easy in PP7, not experienced enough in Connect to find the best solution.

How about creating a new field in DataMapping and use the slice command in JavaScript to truncate the value of the full/source field.
