Transcribe audio channel separately

I would like to suggest an addition to the audio transcription feature. Currently, the transcription functionality treats stereo audio files as a single entity and transcribes the combined channels. However, it would be incredibly useful if there was an option to transcribe each channel separately.

Use Case:
When working with stereo audio files, it is common to have distinct information or voices recorded on different channels. By transcribing each channel individually, we can extract and analyze the data more effectively. This feature would greatly benefit developers, researchers, and anyone working with multi-channel audio files.

Expected Behavior:
Upon uploading a stereo audio file, the transcription tool should provide an option to transcribe channel 0 separately and channel 1 separately. This would allow users to get accurate transcriptions for each channel and save considerable effort in manually separating and transcribing them.
