In creating a form the other day, I came across an instance where it would be extremely useful when a user selects an item in the source field via a dropdown selection, it not only shows the needed fields for that specific item, but it also pre-populates the correct information that would also be stored in the target fields via a dropdown list. This could greatly save time in entering data that always stays the same for the source field data. I recommend that this be an added feature to forms to help with automation and reduce the time a user needs to fill out a form with data that doesn't change, but has to be captured for the source field.
