Randomize file names when uploading

I would like to be able to have the option to randomize file names to random string of letters/numbers when uploading. Maybe like a box you can check like spoilers or a setting for your account. I'm sure there could be more uses, but my main reason is that when I upload screenshots from something like ShareX, the file names automatically include the software and exact time it was taken. It could save me a bit of time renaming them, and I rather like the file names assigned for archival reasons.
