Dish Interactive is from Nss6 and not from Insat. You can get Insat & Nss6 at the same time without moving the dish and that you have already done. To get other satellites like ABS1 or Panamsat 45E you need to move your dish or you can add another dish.
For now there are no satellites between Insat 4B and Nss6.
