Doing so requires subclassing the queryset object.  This blog post describes the issue in more detail and proposes a solution:

It would be helpful if there were an officially approved way to subclass querysets or add custom chainable filters, and it was part of the documentation."	New feature	closed	Documentation		Normal	wontfix		mike@… ognajd@…	Accepted	0	0	0	0	0	0
