Hi Khan,
It came out in 12.0(7)T. It is typically used in conjunction with
Site-Of-Origin (SOO) communities in MPLS-VPN networks where you have
multiple customer sites with the same AS number. But it will do what you
want for the example you gave. Be careful in production, though.
Removing/modifying path information via overide or aggregate summary-only
can cause loops.
