But I would have to question your statement: "Milwaukee's varies with
runway
usage. Sometimes it's along runway 7/25, sometimes it's along runway
1/19".

How often would a pilot know the active runway prior to calling Approach?

Seattle has a similar situation. Before calling Approach, you listen to the
ATIS, because the sector divisions (some of them) depend on which direction
the traffic is flowing.

So the answer to your question is: listen to the ATIS. It's not like they
are keeping the active runway secret until you actually talk to them.
"Seattle Approach, Cessna 12345, 20 miles west, 2000', pssst what runway are
you guys using?"
