When transcribing an audio/video file, one option is "Import Transcript". When you select this option, you must paste your transcript into a dialog. In our case, we've already transcribed an audio version of our podcast using Descript, and want to use Descript to edit the video version... but we don't want to transcribe the same podcast twice!
It would be excellent if we could select an existing composition as the source for Import Transcript—it saves the trouble of exporting the composition and then pasting it back into the Import dialog.
