It is impossible to select multiple Placemarks and move them into an existing folder. You must use the Group function, which create a new folder.
If you want to move multiple Placemarks that are inside different folders, you must do it one by one.
It would be useful to be able to drag-and-drop multiple Placemarks that are from different folders into an existing folder, like this.
In this example, there are only a few Placemarks. But if you have to move dozens or hundreds of Placemarks, it becomes painful to do it one by one.
Thank you !
