Multiple streams of one type: avoid 'copy.mp4' in the filename?

[outhud]

If I want to download two video streams (for example 1080p and a 720p) from running N_m3u8DL-RE once, it works but the filename for the one which was downloaded second just has .copy.mp4 at end of the filename. If I add a third video stream to download, the third one is .copy.copy.mp4.

Is there a way to add the resolution information to the mp4 output? Instead of having to guess from the filenames or sizes which one is .copy.mp4 and .copy.copy.mp4 ?

Using --save-name just lets me specify a static save-name, so it still uses .copy.mp4 with that.

It gets more complicated if I want to download multiple audio streams or subtitles. They end up with .copy.m4a and it's difficult to tell which is which from the filename.
