I believe that modifying outgoing updates is changing the MED. Which should
"suggest" to your upstream AS which route to take back INTO your AS.
I have the opposite. I want to influence MY AS to send a particular route
out of a particular router. It may not be the closest exit point of my AS,
but I want to force this behavior.
