This has been requested for an enhancement.
My feeling is you should be able to point to a temp variable or even an inbound or outbound field as the source for the list.
As it is, the list function is too constraining. I rarely hve a use outside of generating test data for the list iterate because of its fixed nature.
I would have had a few rather neat uses if it were more flexible.
