Thanks to everybody who replied, I'm glad to see I didn't miss anything.

I do actually have a reason for wanting a single format pattern, but I can
probably work with what I have, it will just be less convenient.

I hesitate to suggest this, what with the whole PEP procedure and all
being so intimidating to those who aren't familiar with it (e.g. me), but
would there be any interest in extending the formatting operations to
include such a feature? It would (presumably) break compatibility with
printf, but does that matter?
