Bingo, Marc! Great answer! Like I said, I figured I was missing it.
Right there in the documentation.
A note about it, though. It appears there is a character limit on the
detail file name used in the import instructions. No biggie as I just
copy the file locally and then get rid of it, but still a limitation.
I'm going to try a couple of other tricks to see if I can get it to
accept a path'd name.
Thanks again, Marc, y'all are great!
