You know, that's a feature I've never used. Let me check.

You are absolutely right: "Reveal in Media Storage" is not something I ever noticed before. You can do exactly what the o.p. has asked for:

Very, very dangerous feature. But I often say, "the power of Resolve is that it'll let you do just about anything you tell it to do... even if the results are calamitous. Permanently deleting entire video tracks and timelines is a good example, and there's no Undo in removing Gallery Grades or Gallery Folders, either.
It's been like 8 years since I permanetly deleted
one camera clip from a client's feature, and it still makes me break out into a cold sweat. Normally, I'm dealing with backup copies, but this was a case where we were still in the middle of the conform, and so I was exhausted and hit the DELETE button without thinking. Luckily, the client still had the camera cards & drives, so we were able to plug in that missing shot. But what if they had already wiped all the storage and he had no backup? We have a "we're not responsible for losing any files" clause in our client contract now, but we didn't 8 years ago.
