P: Making Metadata /Location available as keywords

I'm looking for help with importing location information from the maps module in Lighroom into the keywords suggestions - is there a way to do this automatically - for example a Picture taken in Rome Italy will automatically tagged (keyworded) with Europe/Italy/Rome  - The Location is already conveniently displayed in the Maps module - i assume that the cameras GPS feature has been switched on while shooting the Pictures. 

Making other Metadata available like the camera used would be nice to have 

Having the location automatically available as a keyword (suggestion) would save time and tedious work - up to now this  this step seems to be  needed  carried out  manually - for me it matters as would like to include the location for text based search for stock photography

best regards
