Is your feature request related to a problem?

In the Global Variables menu there is the possibility to select a Global Variable and then
change it's value for all the different Flight Modes.
It would be helpful to have a "button" in the Global Varialbles menu to be able to change all the
GV:s for the active FlightMode, i.e. for the values that are "highlighted" in the Global Variables menu.
