You need it for the Calendar component? If so, you can make the change directly in your PR 😊

If we add this functionality to the current PR, it will end up with me creating the Datepicker just for the documentation.

I think we don't need to make any changes in the documentation for now. When the time comes to work on the Datepicker, we can do it then.

Otherwise, it will result in double work.
