[Prototype]-How to remove audio files from its list? Audio files management?

So... Audio playback and trigger is all great. But due to recurent back and forth in order to test sounds in different platforms (So even if I am ok with my sound design, I still need to know how it adapts to each devices and so I need it uploaded on adobe Xd). The thing is I just stopped to use it for now because I have already 4 duplicates within adobe Xd, each of them with a tiny change. I don't need the previous version of these sounds and I'd like to remove them from the list... Make sens, doesn't it? But where do I manage these files? No idea. Please help me on this or otherwise it'll be hundreds of sounds, most of them versionning of the first one, stacked on this list.

Cheers.
