I have seen slides of a nurseryman who propagates these by leaf cuttings.
Remove the leaf, make a slight cut down the midrib, but not cutting all the
way through.Dust with rooting powder, and lay on a porous rooting medium.
Pin the entire leaf with small pieces of wire onto the rooting medium.
 Enclose the container in a plastic bag, poking holes to allow for some air
circulation , and preventing heat build up.     Some spray a weak solution
of fungicide on the leaf to prevent mildew. Cross your fingers, watch and
wait. Good Luck.
