If you use the area selection tool (control+f in Latikai, at least) and select the entire area you want to wall over, and then release the selection, you can try to place a starter corner on each of the squares (remember to hold down shift to snap it to the grid). In my experience, if you can place a starter corner on each square, and the elevation difference isn't really, really large, you can build a fence normally (using segments instead of starter corners) along the slope as well.
You can also test with a makeshift fence.
