In order to be able to place the current locations of the portraits on the map, the locations and the coordinates need to be added to the database and csv.

Maybe Sam wants to do this?

Ok, the findspot is stored in location, lets store the location where the statue is now in

current_location and add the coordinates in the same way as is done with the import of the database.xlsx file

Place_current / Coordinates_current --> Sam

Sam and Sven will take care of this
