There's always the PDD-NOS category to apply to atypical cases, some of which are atypical because of partial criteria or criteria that only cause impairment sometimes.
Sorry if I'm double-posting, my response doesn't seem to have appeared.
It's my understanding that a NOS diganosis occurs when you don't meet all of the criteria for a particular diagnosis, except for the impairment criteria which must always exist. (The impairment needs to be
significant in the eyes of the assessor, but may not necessarily be persistent or pervasive.)
I could be wrong though, and would be interested in having it clarified.
