Impossible.
The decisions are randomly generated and you get about 1 a turn. There is not a fixed set or certain amount of decision per chapter, it depends on how long you take, which is dependent on how fast you move through the strategy map. Your decisions affect the support you get, which affects the RTS.
Besides, if doing one decision a turn is enough to make you gripe, I can't imagine that you'd like to sit through about 300 decisions in a row before you can play on the strategy map.
