When doing Image Trace, I don't need Auto Grouping. I tweak all the settings, uncheck "Auto Grouping", and save a New Preset.
But after applying that saved preset to the new image, "Auto Grouping" checkbox is still checked by default - and i need to uncheck it every time manually (and that triggers "re-trace") before i click "Expand".
I need to have a preset without "Auto Grouping", but it's impossible to do, since Illustrator simply ignores that check-box when saving a preset.
