Can I set United.com to only list UA metal without listing codesharing flights. I want to reserve a trip overseas and want to upgrade and get the EQM bonuses.

Also can I set my search to always include the longest segments when there is a connection. For example, everytime I look up fares from sea to NY, they always seem to show flights with a connection in den or ord. I'd prefer sea-sfo-ny for its transcontinental service, but I always have to go through the hassel of a multiple city search. Thanks
