It might be possible. The share system on Mac is a little finicky. The reason the feature isn’t there is because on the Mac, you have full access to the file system. So since you can output the original + metadata to a folder, then moving that to another app is simple. On iOS, that’s much more difficult / requires more steps. Perhaps I’m missing something – can you tell me why the copy to a folder and then open that in another app is a significant issue (other than it’s an extra step).
