Editor and tools

[allrounder18]

Ok I am having problem with the loaded objects from another map and that is they are loaded underneath the terrain and when you select these objects one by one and use the snap to terrain tool they get misaligned hence things look messy when you play the map , is there any way to select all the loaded objects at once so that when you use the snap tool they don't get misaligned , I have tried using the select all option but still not working you have to select groups of items one by one
