Two-stage processing was developed to add data from the relation to the member objects, not the other way around. Usually the member has some tags in that case. Your use case is better solved by having some kind of mechanism to access member objects directly from the relation. We don't have such a mechanism yet, because it is not quite clear how that should look and how to implement this efficiently, but I'd look for a solution in that direction. Two-stage processing creates a lot of overhead and is difficult to understand and use anway, so it is probably better not to use it for more and more use cases.
