Or at least advertise the smallest subnets that you're upstream carrier 
will take, Ran into this issue many years ago, ended up prepending 
advertised routes to get traffic to take the path desired where 
possible.

Your mileage always varies depending on scalability and balancing the 
risk of the path taking a far less optimal path to you in the event of 
an transit failure, the joys of traffic engineering.
