In Numbers, I've seen how to change the default cell colour and font, based on table styles.
But how can one change the default number formatting? The default "American" formatting for dates, for example, drives me nuts, and it's often the first thing I change in every new spreadsheet I create!
I would like dates to automagically take on
YYYY-MM-DD format — especially if I enter them that way! But currently, they revert to
DD mon YY format.
