Hi,
Dynamic View should pull in the column Description from the source Sheet and make it the Description/Helper Text, but allow for alternate or no text (via Settings checkbox) if admin wants to describe differently for a specific Dynamic View field.
Helper text is important, but should not need to be maintained in two sources or diverge to different descriptions, and currently I am only aware of a lot of cutting/pasting if I want to build or maintain Descriptions for same fields/columns between DV and a Sheet.
Thanks!
