No like you want it's not possible. You can however make a table. -4 and +4 with weight 1, -3 and +3 with weight 4, -2 and +2 with 10, -1 and +1 with 16 and 0 with 19 Simulates the probabilties of rolling 4 dice without a modifier. You can write -4 as (-4) Abysmal etc. Then you make a table for +1 modifier, it just shifts everything up by one. So -3 and +5 now have wieght 1, -2 and +4 are weight 4 etc. Repeat for +2, +3 etc modifier. Sure it's not exaclty the same as actually rolling 4 fate dice, the endresult is the same, but it looks different so people may not like it.
