Can we disable the aliens abductions and pregnancies in gameplay?

Yes, I want this option too. Not being able to disable alien abductions and pregnancies (as well as illness) is why I haven't got Get to Work. If I could at least turn off the pregnancies, I wouldn't mind the abductions so much. But I don't want to have to use a certain item or gameplay in every save for every househole I play, nor do I want to have to rely on a mod that if it stops working I'm stuck with that feature.
