Yes, but I was under the impression that they were only available
in Tabula.  As soon as we figure out how, they are going to be
available in TinyTables due to their usefulness.

I have done this as an External Method, but I couldn't figure out
how to provide a general solution using External Methods. How do
you tell your filter what to operate on without being specific?
As usual, I'm lost here and probably sitting on the compass...
