It would be nice as an option of some missions. It's especially the case of the missions where you have reach a pop limit on 200 in limited amount of time, and seeing that your pop limit is 200, this is very hard. Maybe an option top pay between 500-1000 empire points to skip those missions. If not then raise the poplimit to at least 300. I have come to a grinding halt at those missions at ALL my civs.
