I wonder why you need to do this. "what problem are you trying to
solve ?"

The OSPF router will advertise a route to its neighbors that makes
all 4 networks reachable. Why would neighbors need to see the
specific x.y.12.0 route ?

If you really need an individual advertisement of the 12 network, as
someone has already suggested, your best solution is to not summarize
to a /16, but to summarize the 1.0, 2.0, and 3.0 and leave the 12.0
alone.
