Hello Nigel: Unfortunately there is currently no way to have different "views" for your monitored resources. So in your example (below), you would probably want to set up a gmetad to aggregate the metrics across ApplicationA (and not by location). You could of course set up as many gmetads aggregating different metrics from different sources, that is solely up to you.
