It should be possible.  I'll look into adding it.

Currently, the AppGraphics dialog Y/N defaults to a "Yes" response, but there are times when the preferred default should be "No" (The default is the button that's highlighted and selected if the <Enter> is pressed.).

Would it be possible to add the option to allow either a "Yes" or a "No" to be the default for the Yes/No Dialog in AppGraphics?
