The purpose is to have something happen for every attacking character by default, without having to manually input the macro into each sheet's field. My larger intention is to use the Unchained Revised Action Economy rules and I want to make attacks more discrete actions in-game. As all players and NPCs would use this, I would have to enter macros into every sheet unless there is a universal way to include them. And if I need or want to change something in the universal macro, I don't want to have to modify it by visiting everyone's sheet individually. For example, in the Global Attack Macro I might want to include: ?{Attack #|1st Attack, 0 [1st]|2nd Attack, -5 [2nd]|3rd Attack, -10 [3rd]} What sort of solution might I need to accomplish this?
