How can i global configuring aws amplify?

Question

I have configuring of storage, but i have one problem with customPrefix. CustomPrefix using for Storage.get and Storage.put. How can i do customPrefix for only Storage.put?

    Amplify.configure({
        Storage: {
          customPrefix: {
            public: 'myPublicPrefix/',
            protected: 'myProtectedPrefix/',
            private: 'myPrivatePrefix/'
          },
          AWSS3: {
            bucket: 'lighting-dev-assets-storage',
            region: 'us-east-1',
          },
       },
    });
