If, for instance, it was toggled by pressing D, then it's easy to assign that keystroke to a labelled GoFlight module button. Press the button and fuel starts to dump, press again and it stops. Sorry, don't think the ACE tool allows us to hi-jack key press ops, I suspect because FS wants to be boss of these, as it allows users to play with them, within the limits of the FS listed events, as opposed to the entire events range.
