Selective map update

Is it possible to have a selective map update? I was in France last week, so in have France maps in my devices.

Of cource I want to use the latest German maps.

For the time beeing, I will not need France map in latest details. So I would like to keep the France maps without regularly updating them.

So now I wonder, if I can only update some selected maps and not only all maps I have in my devices. That will also save my time and bandwidth (1 to 1,5 GB for every download x 2 devices).
