Is there a way to have chatsetattr set the value based on a die roll? For example, I want a variable passive perception roll to be made every time a character rolls initiative that resets their passive peception which is hidden on a tab players don't have access to. This way their passive perception isn't a fixed number (lets face it, with passive perception as a fixed number I pretty much get free will to decide if they can percieve something or not and I want it to be a little bit more random). Something like !setattr --sel --passiveperception|[[1d20 +@{selected|WisdomMod} ]]
