I've been trying to request taxi to a different runway than ATC would like to assign.  I'm requesting a parallel runway so wind should not be a problem. I am picking the available request phrase from the pull down menu and am using the sayit function.  I have the "Force pilot runway selection" button checked.  The response is always taxi to the ATC preferred runway. i've tried this at two different airports with the same result.  Any suggestions? Thanks.

Before requesting taxi instructions, ask for a different runway "<CallSign> request departure runway xx".  You should then get taxi to that runway.

Thanks Dave. Works great.
