Query Object Graph by Levels [message #1102884]

Lets say I have the following object graph:

Bicycle -> Wheel -> Spoke -> Manufacturer -> Address

all 1:n relations.

when I query for the Bike, I also want to load the Wheel objects, but I am not interested in the Spoke Manufacturer and its Address.

But if I load the Spoke, I do want the Manufacturer, and if I load the Manufacturer I also want the Address.
So, with every query I want the Object asked for plus one level down, but not the whole graph.

Is there a way in mapping or designing the query to do this?
