Did you figure this out? When you mention forcing a read do you mean just performing a read? I haven't worked with triggers before but I would suspect you could set your trigger for a certain set of criteria and still perform a read of all the AI channels. You would want to put some protection around your code to make sure your trigger even can't occur during a manual read but that would just be some basic source code I think.
