When I get multiple shooting dice for one action, e.g. due high Rate of Fire, Fanning or using double shotguns, do I have to assign each individual die to a specific target before the roll, effectively rolling them individually (or having the need for different colors to assign), or can I roll them all at once and decide after the result which one affects which target? Do I resolve one die before rolling the next, so do I have to gamble when it is the best time to use the wild die as replacement, or do I first roll all dice (if necessary keeping track which die goes to which target), and then pick the one I want to upgrade with the wild die?
Or is it sufficient to declare the targets of the shot, but assign the actual dice after they are rolled as a pool together with the wild die?
