row_number() on flat file data source?

I have a flat file data source. I'd LOVE to use row_number() OVER ( PARTITION BY id ORDER BY id ASC ) against my flat file data source. But when I do, I get this: Finished with error: Error executing view: Function row_number is not executable I saw another post stating that analytic functions are delegated to the source, but what if the source is a flat file? Is it on the roadmap to be able to perform analytic functions (like row_number() over ()) against flat file sources?
