Partial update

Can you make a partial update?

I have a class with a name, a deleted flag and a relationship to related rows in another table. If I just want to change the deleted flag, do I really have to populate the entire object before saving, as it seems now that my empty name and empty relationship is also saved causing the whole data structure to be corrupt.

Would it be achievable if I created another object not containing the relationship and/or name? Would that cause only the actual properties to be updated?

There are no plans for partial update yet.
