That's how I do it. I center the backing on the table (unless it's a wallhanging, it hangs over the sides of the table), then I use large binder clips to keep the backing taut. I center the batting over the backing, lift up one side of the batting, spray and smooth; then lift up the other side, spray and smooth. I then center the top over the batting, lift up one side, spray and smooth. I then unclip the binder clips, move the whole thing to on, clip, lift, spray, smooth, repeat until the whole quilt is spray basted.
