Can I loop a music segment using markers ?

Question

I have a single WAV file to be used as a BGM. My goal is to setup a normal loop in the track, by setting loop start and end markers.

However, the Source Editor doesnt allow me to set loops, because they are already features of the Music Segment and Tracks editors. But those editors dont even allow for anything other than custom cues, which are pretty useless outside of transitions.

Is there any way for me to loop a specific part of the music with the Interactive Music Hierarchy ? I know a Music Playlist container can loop segments, but those loop the entire track, not a segment infinitely.
