You can't. This is ticket #4260. I'm still working out the full API for it (I've spent a bit of time on it this evening, coincidentally). Don't be afraid to write custom SQL. Remember that Django's ORM is intentionally not designed to be a 100% replacement for SQL, since SQL already exists. So, from time to time, it's faster to just write the query.
