Difficult navigation on the map if the boulder crag is very spread out

When the boulders of a crag is spread out over a big area the boulder-markers disappear from the map when you zoom out. That makes it very difficult to navigate around and locate boulders because you kind of have to know where they are beforehand so you can zoom in on them. As it is no you end up panning around the map randomly until you accidently locate a boulder-marker. I know this is not a problem for most crags but I had the problem with the crag Gjerdalen in Norway.
