Nested Filter in Expand (OdataV4 feature)

Nested Filter in Expand

OData V4 supports nested filters in $expand. The request below return People with Firstname "Bart" and all their trips with Name "Trip in US".

GET serviceRoot/People?$filter=Firstname eq 'bart'&$expand=Trips($filter=Name eq 'Trip in US')

Working example from publicly available OData v4 endpoint here (http://services.odata.org/V4/OData/OData.svc/):

http://services.odata.org/V4/TripPinService/People?$filter=LastName%20eq%20%27Calabrese%27&$expand=Friends($filter=FirstName%20eq%20%27Scott%27)

how can I get the same result with current SAP Gateway?
