This is not likely to be storable in rhizopod. Maybe sardine.
You could of course implement this in a program that uses the rhizopod
hub, but it would require a "system_type" or some other attribute to
the UCS entity which would not be preservable across conversions.
Regardless, the entities will always be stored in world coordinates in
rhizopod, so the usage of this would be up to the program (e.g. the
entered coordinates would have to be calculated into WCS before
storing them.)
