For me, that would be perfect. I’m not sure that I would force it to be an all or nothing option though as I am sure there will be people who need to apply it to certain products only. I can’t imagine a scenario when that would be needed, but I am sure that it is out there.
How about adding a column to the CSV file that allows you to control this? i.e. You put “Yes” or “No” in the ‘auto-hide’ column. Or maybe a 1 or 0 or something.
