I've been using sidekick for "table selection" in games but there's a tiny snag. I really want only unique results for each. As far as I can tell, the only way to do this is to reroll until the RNG decides to give me a different value, which is annoying.

Therefore I suggest something like this

/r 3d8u

Where if you put a u at the end it will reroll any non-unique rolls, giving you different numeric results for every roll.

Is this something you could possibly add?
