A vital part of the BB combat round is the ability to re-roll specific dice in a recently failed roll (the "Advantage"). However, there is no way to select individual dice from the previous roll, nor any way to specify which ones to re-roll. It *is* possible to visually inspect the die roll, figure out what size dice needs to be re-rolled, announce that to the other players, and then type "/roll d x ", of course, but that's kludgy and will get tiresome after the first few dozen times. (anyway, seems odd to build an RPG from the ground up to be compatible with Roll20 and then deliberately add a mechanic that is *not* compatible with Roll20 without a lot of scriptwriting and/or kludging?)
