Hello…
I have suggestion, it’s simple and take little time, probably ^^.
Actually we can use this function :
SobGroup_AreAnySquadronsInsideDustCloud
SobGroup_AreAnySquadronsInsideNebula
SobGroup_AreAnySquadronsOutsideDustCloud
SobGroup_AreAnySquadronsOutsideNebula
BUT, we have not this function :
SobGroup_AreAnySquadronInsideVolume
SobGroup_AreAnySquadronOutsideVolume
You understand what this function return : true if ship (one ship of the sob group) are inside volume for the first and false else. true if outside for the second and false else.
So, it’s judicious to add this in the next big patch 
(Because actually, to verify if the player have send ship in the volume, i need to place Nebula (hiding) in the volume to use other function, and i don’t need this nebula … )
