Much needed hotkey for manning the flak guns

[Paul Riley]

As aircraft are becoming significantly more frequent and persistant in my campaign now,a hotkey for quickly manning the flaks would be a neccessity I would think,is there a way to do this?,or maybe it is included in GWX?It would certainly make life a lot easier,instead of having to hover over the man guns button nervously,waiting for...you know what

I can't believe it's not included in the list of keys,I think its probably one of the most important hotkeys I can think of

Thanks.
