Invoice Date Field to show whole Date Year

Could we have the Invoice Date - [Invoice Date] field to show the whole date i.e. 16/06/2020 not just 16/06/20 or have a new field created maybe call it Invoice Full Date or something similar?

For the time I have typed in a 20 at the end of [Invoice Date] field i.e. [Invoice Date]20

Thanks,
Ivona
