The 'usual' way to do something like this would be to set up a single 
static route as a blackhole (eg: 192.0.2.1/32 -> blackhole) on your 
router(s) and then use BGP on another machine to actually inject the 
routes into your network with a next-hop of 192.0.2.1.

Something like exabgp can be used as part of the tool on the non-router 
machine to get your list of hosts into BGP - I've not looked, but 
something to do what you want may already exist somewhere.
