How to group countries by areas in map view (excel 2013)

Hi,

I'm working with map views in excel 2013 and I would like to create my own geographical areas, not the existents areas in the maps.

For example, I have an area called "far east" which has the following countries: Australia, Bangladesh, China and Honk Kong.

I need to be able to see this area in the map when I select this in the characteristcis previously loaded from my data table.

Can anybody help me?

Thanks in advance.
