How do you position an imported tiled Landscape

Greetings,

I used L3DT to create the terrain for a wooded forest which I would like placed at the edge of my city. In the image below the large grey mesh is the imported tiled landscpe. The problem is when I go to levels and use the import tiled landscape feature, it will only place the landscape at the origin directly in the center of the city. If I try to modify the X & Y coordinates when entering the import parameters the landscape will not import at all. The terrain is 2km x 2km and I’m also unable to use the move tool to properly position it on the edge of the map after it has been imported .
