Modifying Map

[Vassago Embrace]

I have a full Smart Image map with pins of a nation in one of my RW realm. I have now found a much more detailed map of such nation, with more labels than the one I am using.

Is it possible to access the map on Realm Works with a map maker software to modify it? Where are the maps stored in RW?

My goal would be modifying the map by adding manually some labels, and then go back to RW and create new pins for the newly created labels. In this way, there would be no need to import a new map and putting all the pins all over again.

Is this something possible? If not, how would you go about to solve this problem?

Thanks is advance for your insight!
