Can Cortana be set to accept something other than ;Yes' as the affirmative response?

[WPCentral Question]

I'm just trying out cortana for the first time, and already I'm annoyed by having to tell her "yes" to confirm my instructions..... Can I set the expected response to something else? for instance "Perfect"

I agree. I would like to confirm by just saying 'Thank You'. It would also be nice if she replied with 'your welcome' or something.
