When is the best time for using an CRTL+SHIFT+W on departure. I find that when I issue ground 0 command, I get the departure runway assigned by ATC and then co pilot reply by repeating the ATC, but if I want to request a different runway, I only have a fraction of a second to issue an CRTL+SHIFT+W. A lot of time I get a "skip the next taxi way". When is the proper time to ask for a different runway? Is there a option to allow more time to use CRTL+SHIFT+W for a different runway request.
Thanks
