Is there any way to access "route" object "placeholder" data and add new properties inside "route" object before sending the final response? Or Is there any way to access "route" object inside custom processor inherited from JssGetLayoutServiceContextProcessor (for customizing "context" object) so that I can add custom properties based on "placeholder" data of "route" object. Basically I want to reuse already created JObject from rendering resolvers before sending final response.
