Add port number to DNS?

[AppleBag]

Does anyone know how to include the port number when filling in these 2 DNS fields?

And if I do include the port numbers, will it actually make use of the port number I add, rather than still defaulting to port 53?

Not possible in the router nor the DHCP spec.
