Yes, What I wanted to do was have a field in my Category model called num_entries, and every time an Entry model was saved, I wanted to increment this by one - but I could not work out how to access the Category model to update just one field per entry (for example if my entry is in Blog and Django, I want to update each blog_categories.num_entries field for that row).
Hope that makes sense, as if I can do it this way instead of calculating it on the view, that would make this inclusion tag so much easier.
