Yes, I've seen variations on this used in lessons before, including by my own coach. String a rope across the court. Rally shots from behind the baseline were supposed to be over the rope and when attacking from inside the baseline hit under the rope. Otherwise I've seen coaches bring portable volleyball nets onto the court and have students rally baseline to baseline over it.
