How to unmarshal query response into protobuf struct using dgo

Hi there,

I would like to know if there is a way to unmarshal a query response directly into a protobuf struct (the same used to insert data). In the code below it will only work if I create a new struct and define contract field as an array.
This was previously possible using client.unmarshal, I can see how moving to json makes it consistent across all clients but I believe being able to insert and query data from dgraph via grpc and protobuf (without any additional code) was a great feature of the go client.

// PB definition
//
// message European {
// 	double timestamp = 1;
// 	string ticker = 2;
// 	string undticker = 3;
// 	double strike = 4;
// 	double expiry = 5;
// 	string putcall = 6;
// }
//
// message PriceRequest {
// 	double pricingdate = 1;
// 	European contract = 2;
// 	OptionMarket marketdata = 3;
// }

func Test_contractRequest(t *testing.T) {
	resp := query(
		`query ContractRequest($optionTicker: string){
			contract(func: eq(ticker, $optionTicker)){
				ticker
				strike
				undticker
				expiry
				putcall
			}
		}`,
		map[string]string{
			"$optionTicker": "AAPL DEC2017 PUT",
		})

	priceReq := &pb.PriceRequest{}
	// Fails with error "json: cannot unmarshal array into Go struct field PriceRequest.contract of type pb.European"
	err := json.Unmarshal(resp.GetJson(), priceReq)
	if err != nil {
		type Root struct {
			Contract []pb.European `json:"contract"`
		}

		root := &Root{}
		// Works fine
		err = json.Unmarshal(resp.GetJson(), root)
		if err != nil {
			t.Error(err)
		}
		t.Log(root)
		t.Fail()
	}
	t.Log(priceReq)
}
