Sorry for the slow reply. At the moment, there is no way to specify
that. (Unless you can use a default manager to do it, but that might be
constrained by other things).
It would be nice to come up with a better API for this kind of thing.
SQLAlchemy may have some good ideas in the way it does eager loading - I
believe it has support for equivalents of both select_related and
prefetch_related.
What I'm saying is that in the absence of that better API, or some way
of specifying the query you want, we shouldn't guess and convert one
optimisation into another.
