We are doing better at bumping isotope-numbers. There's this list of heavier lanthanides: thulium-182 and -183, ytterbium-186 and -187, lutetium-190. Maybe not useful in of themselves; but they're giving us insight into what merging neutron-stars cough out.
Really these techniques look good for stabilising nuclear waste. Japan seem most-interested in this, as they're reintroducing fission reactors. Stable elements are still hot to handle, and would probably have to be stored longer; but they are less hot to handle, so can be more-safely carted off to storage.
