Hide Specific Images in Upload Preview Pane

When uploading images to Discord servers and channels, Discord provides an in-app preview pane for quick access to the images stored on the device. The problem is, it doesn't descriminate based on, for example, where the images are, or whether or not they are in a "hidden album." The ability to select specific images and hide them from appearing in this pane would be immensely helpful. It would be nice if there were a way to have Discord respect whether an album/folder is hidden in the Gallery, but even having to go through and hide every individual image I'd rather people not shoulder surf on would be preferable to the lessaiz faire, no holds barred, all out-in-the-open free-for-all that is the current system. Honestly why this feature wasn't included at the start is beyond me.
