Permitting specific prefixes in BGP

I have a router that I want to announce 10.0.0.0/8 as an aggre-
gate. This will suppress tons of other networks. But I also want
to unsuppress a couple of specific networks (e.g. 10.12.0.0/16)
to a specific peer.

I've tried using

 router bgp 1010
   aggr 10.0.0.0 255.0.0.0 summ
   neigh a.b.c.d unsupp NETS-LYNG

 route-map NETS-LYNG perm 10
   match ip addr ip pref NETS-LYNG

 route-map NETS-LYNG deny 20

 ip pref NETS-LYNG permit 10.12.0.0/16
 ip pref (etc).

But that doesn't seem to do the trick, as that also unsuppresses
10.12.1.0/24, which I still want to be suppressed.

Any ideas?

TIA,
-A
