I have a date field, and I would like to transform it into a single selection field with the same format as the date, which is dd/mm/yyyy. Whenever a new value is added to the date field, I want the single selection field to be updated accordingly.

The format after type conversion from date field to single-select is always YYYY-MM-DD. And updating single select field options dynamically when date field is updated is not possible directly. You will to rely on webhook & monitor date field for any changes & then use API’s to update select field options.
