It's already there and has been for many years. Use a host statement
with a hardware ethernet statement to match against, eg in the
minimalist form:

host host_label {
	hardware ethernet aa:bb:cc:dd:ee:ff;
	fixed-address 192.168.0.1;
}

The host statement will automatically pick up options, such as
routers, from the corresponding subnet declaration.

A couple of beers will cover the cost :)
