Is there a way for Pages to display an auto-updating date in ordinal format? I am currently putting together a template document in Pages and would like the date to update each time it is opened.

However, I would also like to display the date as an ordinal number (for example, today would be 11th September 2012) which isn't in the list of available formats.

Does anybody know of a way to set the date to auto-update in this format or do I have to manually set it each time?
You can set the date to update every time the document is opened by double-clicking on it, and selecting “Automatically update on open”. As for making the date ordinal, I don’t think it’s possible or would require heavy plist modifications or may depend on your localisation settings.
