Jersey: Inject parameter similar to how @Context works

Jersey injects the request context into any argument annotated with @Context. Is there a way I could do something similar using reflection e.g. create a Jersey Filter/ContainerRequestFilter or MethodInterceptor which would allow me to inject custom parameters such as user below into my resources?

@Path("/")
public class SomeResource {

    @POST
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    Response postSomething(@User User user, @Context UriInfo uriInfo) {
        // Do something with user
    }
}

I considered using a ContainerRequestFilter like:

@Provider
public class UserFilter implements ContainerRequestFilter {

    @Context
    private ResourceInfo resourceInfo;

}

But I cant see a way to get and modify the method arguments using ResourceInfo
