## Combinar retornos predefinidos e personalizados { #combine-predefined-responses-and-custom-ones }

Você pode querer possuir alguns retornos predefinidos que são aplicados para diversas *operações de rota*, porém você deseja combinar com retornos personalizados que são necessários para cada *operação de rota*.
