This is not about automatic synchronization. That’s of course a far 
longer shot, and there’s already an issue for it (don’t want to search 
it right now).
If adding a simple switch for odd-only/even-only is only syntactic sugar 
of sorts for functionality that with some effort is already available, 
that’s all the better, then this is only about designing the interface.
