Changing default date dimensions

Hi, just wondering what the best way of changing Date Dimensions to allow for different financial reporting periods in Australia.  The default in GoodData uses Calendar Year Quarters for example.  ie. Jan 2023 is Q1-2023, whereas for financial reporting purposes in Australia Jan 2023 is Q3-FY23.  Aside from creating a completely new Date Dimension table, is there a way of working with the default.

Thanks.
