Currently no operations allow for combinations or permutations of grouped fields within the aggregation pipeline. MapReduce currently doesn't support multiple values returned as part of "reduce", so it's not an option at this point. However, it would best to have this implemented as part of the aggregation pipeline so that other operations can be chained like sorting.
