In general, you should edit your original question to clarify why it's not a duplicate rather than bringing up a new question. If you can't do that convincingly, the question will remain closed… because you did not convince enough people (5 with 3k rep, or 1 with a gold badge or diamond) that your assertion that the questions are different is correct. (This was explained on the answers to the other question, incidentally.)
But a feature-request for a feature that already exists is definitely a duplicate of a support question asking what feature to use for the same purpose — both are answered by pointing to the appropriate usage of the existing functionality. Which you should be using, rather than asking for a feature that already exists.
