Ah, composite actor did the trick in so far as putting that WF in another, i see it can inherit the directory (as I did in my experimenting and checking docs), but I notice it doesn't "fire" when you run the main work flow. (it has its own controls). It would be nice if when I run the outer WF, that the composite ones run too. Probably I am missing something simple?
