Side Loading Audio Tracks in AVPlayer

I am able to load audio tracks that are in the .m3u8 file.

I have an external audio track URL that needs to be loaded in AVPlayer.

Is there any way to add it to the tracks of AVPlayer like Exoplayer have an option to mergesMediaSources.

The same problem can be applied to other types of tracks(subtitles, videos etc).
