If you vote to close a question because it is off topic at Network Engineering SE, but on topic elsewhere, there isn't really a built in consistent way of indicating where that question should have gone.
What are the chances we can get ServerFault and Stackoverflow added as options instead of just Meta? Those are the most common overlap stack exchanges we get.
I feel its more helpful to say "This is off topic here, but on topic there" than it is to simply say "this is off topic here".
