title: Batch request using Retrofit
body: <p>I'd like to perform batch request using Retrofit. It there any nice way, how to achieve it? Basically what I'm trying to do is to replace some characters in query part of URL (replace block is allowed only in path part of URL - using <code>@Path</code> annotation). </p>
  
  <p>Here is a pseudocode for my problem.</p>
  
  <pre><code>@GET("/v2/multi?requests=/users/self,/venues/search?client_id={client_id}&amp;client_secret={client_secret}&amp;v={v}&amp;ll={ll}&amp;intent={intent}&amp;limit={limit}")
      ProfileSearchVenuesResponse searchVenuesAndProfiles(@ReplaceBy("client_id") String clientId,
                            @ReplaceBy("client_secret") String clientSecret,
                            @ReplaceBy("v") int version,
                            @ReplaceBy("ll") String location,
                            @ReplaceBy("intent") String intent,
                            @ReplaceBy("limit") int limit);
  </code></pre>
