funny thing is that this ""feature"" was on my bullet list for v2017 training yesterday. But I forgot to make note of ""how"" to turn off the question to remove the form and continue. So I told my client I would have to do some research. Now I don't; thanks for sharing. :)
My notes say it was added in v2017 (not the PU1); and is for both 100 and 100c.
