GoFlight EFIS - Changing BARO from IN to HPA

G'day,Because the BARO knob on the GoFlight EFIS is not double concentric (or whatever ...) changing from IN to HPA is not possible. What is the intend solution in order to change from IN to HPA ? Do I have to continuing clicking with the mouse on the EFIS panel (I know how to do this but it's hard to do it when I've got hardware...) or set-up a keyboard shortcut ? I assume it is not possible with the FS2004 B737NG and B744 to permanently change the default from IN to HPA so that changing it is not necessary (I fly in Western Europe and only need HPA) ?CheersChris.
