> When {{GoogleCloudStorageToGoogleCloudStorageOperator}} is used with a wildcard, it can copy more than one file. It would be useful if there would exist a mechanism to store the list of copied files as XCom so it can be used by other tasks downstream.
> Proposed solution: Add a {{xcom_push}} flag argument to the constructor; if {{True}}, the {{execute}} method returns a list of two-tuples representing each source/destination file pair:
> {code:java}
> [
>     ("original/file/path.ext", "target/prefix/original/file/path.ext"),
>     ...
> ]{code}
