Drill up/down on a Shape map/custom map
Allow drill up/down capability on a shape map/custom map by creating a hierarchy just like on a normal map visual.
When drilling down using a hierarchy on the standard Bing map, from country to city to postcode in certain countries e.g. Netherlands and Belgium then the sites disappear when you go into the postcode level even though they are valid post codes. Also the map allows you to show the amount of data but not the values of data.

Absolutely necessary, as we have a map and, after clicking in a point of interest, it would drill down to a new dashboard (or even a new page/ tab).
