Numbers auto date on template only Is it possible to use the =today() function (or something else) to insert the current date but then not update each time the file is opened?

I want to create a numbers template for my invoices. I'd like it to auto fill invoice date and date due then, when I save the document, store the values, not the function.
Go to Insert > Date &amp; Time.



Double-click the date and format to taste. Make sure "Automatically update on open" isn't ticked.
