If I remember well, MPC-HC (available for Widndows only, but open source) also had it:
https://github.com/clsid2/mpc-hc
I used it with a few external audio tracks (other languages dubbings).

Anyway, until this is added, anyone who really needs an external audio track, if the container is Matroska (.mkv), the track can be muxed in with MKVToolnix and then it will be seen by Haruna too.

MKVToolnix can read basically everything. The input format isn't limited to mkv.
