Is there any way to set a loop point on tracks in resource packs?

[Tèrra~]

Hi! I'm currently making a resource pack that replaces most of the music in Terraria with music from Cave Story and Cave Story+.
Like many games, most songs in Cave Story has a repeat range after the intro to the song, and rather than looping back to the intro when the song finishes it loops back to the start of the repeat range.
I've tried a bunch of stuff to make the tracks loop correctly, but to no avail.
Is it even possible?

As far as I know, this isn't currently possible.

Alright, thank you!
