Makes perfect sense. I never thought to input anything in those boxes, I just imagined they were set with the units
One thing I didn't understand. It seems the sub unit box would not update unless I changed the "Label Format" (MU Label SU Label to MU Label-SU Label, or vice versa), save, yes/all, then back to the original Label Format.
Example: ' and " work, then I changed ' to guacamole (MU) and " to salsa (SU), save, yes/all, guacamole would change and not salsa. Unless I changed the Label format then save, yes/all, then back
But it works!
Thanks
edit:
maybe its the trial version I'm on
