You can do anything in the editor. I can simply explain how to configure sounds and textures in the editor without unnecessary tricks.
P.S. If the sound suddenly doesn't work (;)), remember my words.
I've studied the structure; the game somehow converts them into bin files using the UID, but I can't figure out how to do it correctly. I want to create voiceovers for the intro sequence when the map starts and possibly for dialogues.
