@shoyer see my PR trying to implement this (#2553).

Inputting a list of lists into auto_combine() is working, but it wasn't obvious to me how to handle this within open_mfdataset(). A few approaches:

1) I could try to somehow generalise all of the list comprehensions in open_mfdataset(), which would be messy but general

2) Write some kind of recursive iterator function which would allow me to apply the preproccess and dask.compute functions to all the objects in the nested list

3) Separate the logic so that the input is assumed to be a flat list unless infer_order_from_coords=True

4) Always recursively flatten the input before opening the files, but store the structure somehow
