I've worked with kevin to implement this in some of his workflows.
I've also packaged a custom R actor called "UnionAll" that performs this basic
table stacking (in HEAD only).
While it might seem like a hack way of doing the concatenation, it also seems
very workflow-oriented in that each piece of the concatenation is explicitly
laid out (there's an individual EML data canister on the canvas for each and
every table that is being concatenated).  Sure, there's an upward limit to how
many canisters you want to have on any given canvas, but there has to be some
mechanism for specifying exactly which data tables are being included in the
union and this one happens to be using pretty pictures.
I've marked the with the semantic type of:
