Moscow post office sub-stations 1913-1915

Does anyone know if the Metropol Hotel ever had a post office sub-station or branch located on it's premises during 1913 - 1915? Any recommendations on reference material on sub-stations during this period? I checked "The Postmarks of Moscow, 1765-1917 but could not find much information on sub-stations. Thanks
