Typically you would use a Transform Input Shader. The output of the node(s) that you want to move go into the input of the Transform Input, then enable Translate in that node's settings. Then you just need to work out how many meters in X and Z your target point (within camera view) is from the current location of the feature in question. There's a line measuring tool which may help (ruler icon on the 3D preview toolbar). Enter X and Y distances into the Transform fields that match the distance you need to move the feature along each axis.
Alternatively you can convert the feature to a heightfield and you can full positioning capability with the manipulation handles in the 3D preview. You'd start by adding a Heightfield Generate, positioning it at the location of your desired feauture, and feeding the output of your terrain node(s) into the Shader input. You may need to adjust the size of it in meters to cover the area you need, you'll see it change in the 3D preview if you do. Then click Generate, right-click the Heightfield node, Save As, save it as a TER or EXR, then you can load it with a Heightfield Load and position it wherever you like. You can use right-click in the 3D Preview to copy coordinates for easier repositioning of the heightfield if desired (copy there and then paste into the heightfield's position parameters).
