Distinguish manual vs auto-generated transcripts in metadata

I want a way to distinguish between manually uploaded transcripts and auto-generated ones in the metadata (specifically in the transcriptLanguages array). Currently, I have to iterate through all available languages using mode=native to find a manual one and avoid 206 errors or unwanted AI generation costs from mode=generate. It is difficult to implement this iteration when there are 50+ languages, and the first language in the list isn't always the native one. Adding a 'type' or 'isManual' flag to each language in the metadata would allow me to target the correct native transcript directly.
