Can we set clusteredBlocks throughout the map and not only on visible map rect?

[ShahVivek]

we have below code
for ( REVClusterBlock *block in clusteredBlocks )
{
if( [block count] > 0 )
{
if( ![REVClusterManager clusterAlreadyExistsForMapView:mapView andBlockCluster:block] )
{
[newPins addObject:[block getClusteredAnnotation]];
}
}
}

return newPins;

in + (NSArray *) clusterAnnotationsForMapView:(MKMapView *)mapView forAnnotations:(NSArray *)pins blocks:(NSUInteger)blocks minClusterLevel:(NSUInteger)minClusterLevel
method.

How can I manage the clusteredBlocks so that they deal with the whole map and not only on visible rect of map.
