There is nothing wrong with the carriers, so I wouldn't want to mark them.
Just no route to destination type scenario.

I like daniels option with the drop on_branch.  Only challenge I have is
keeping a list of all the flags I have already tried.  Say I have five
carrier groups and I set the flags in gw to 1 2 3 4 or 5 respectivley.  How
could I use an AVP to efficiently keep a running list and then check against
that list?

Thanks!
