How to disable a sound in world editor?

[ZaWarudo]

I made a trigger for a sound in my map (first time using the editor, barely getting the hang of it)

The sound plays, yes. But it's accompanied by the "job's done" sound. How would I go about disabling it for the whole map?
Also is there an easier way to assign a sound to a finished structure

Maybe replacing the Internal sound of "Job's Done" by an Empty sound?

Genius. Thank you.
