ah, ok - now I got you. Well, how should that work? How would the 
repository know which "group-object" to use and map the results to? Can 
it even be a group-object? How would you access a certain group then? It 
could probably be an array having the "groupBy-value" as key and a 
objectStorage as value.
But I'm not sure if this should be a built in repository feature, should 
it? It probably could be part of a service delivering grouped objects, 
but it might also be in the scope of the view (depending on your other 
needs) and that's what the groupedFor-viewHelper is meant to be used for.

"setReturnRawQueryResult" right - never remember the correct wording.
