[Feature Request] Random Set selection in simulator weapons.

[Shivaan88k]

The Auto Random function is awesome, reminds me of when I was a kid playing with friends we would do custom, then pass the controller around to pick random weapons. Then I remembered that we would also just close our eyes scrolling through the sets as well. So on that note, it would be great if rather than utterly random, it would just shuffle sets, each time you Start/End. But rather than change what is already working, just add a set called Random Set.
