For example: when the Power BI data model first creates a column with Data Type = 'Date', by default that column is formatted like 'Wednesday, March 14, 2001 (dddd, MMMM d, yyyy)'. Then, I always go to the Modeling tab, and use the Format drop-down to change it to '2001-03-14 (yyyy-MM-dd)'. Instead, I would like to be able to go into the "Options" menu in Power BI Desktop, and have a section where, for each Data Type (or at least Date, Date/Time, Decimal Number and Whole Number), I can set the default Format. So that I don't have to manually change it every single time! It would also be nice to add this as a setting in the Power BI Service. Set default Formats (maybe for the entire tenant, or maybe by user?) when creating a data model using the Power BI Service.
