Some (many?) do, or failing that at least hold the lat/long of the airport reference point. FWIW our preferred option is to align using the current GPS position but as there's still a verification process.
On some types/SOPs the manual longhand entry of Lat/long for alignment is seen as something to be avoided if at all possible( for obvious reasons). If that it has to be done then there's usually the need for extra checks to trap errors.
