When having a non static command in a monobehaviour with MonoTarget set to single generate an auto overload with an additional last parameter to specify in which game object the monobehaviour's command should be called
I think the best way to do this would to have a new MonoTargetType called Manual in which the command invocation will take an array of targets too, the only problem with this is it changes the command signature (or adds a new invocation syntax extension entirely) and thus isn’t trivial to fit into the current system
This can now be done with the new MonoTargetTypes Argument and ArgumentMulti in V2.6.5+
Not sure of a good way to do it but I'm a fan of the general idea. Opened for now
