I don't think so mainly because the routing node doesn't know the full path.  I know you can set ignoreNode in eclair and "exclude" in lightning-cli pay  but those are for building a route for your own payment. 

 Yes, that what I wanted to do 

 Yeah exactly, disregard my last note -- we'd have to add route awareness in order to do so and that is something these folks would *love* for us to do.
