Option for C section?

Rachel • 28. Married. SAHM. 🌈Twins Mark and James 9/18/17🌈
I've been looking but I can't find a place to put in the date for my scheduled c section. It would be nice for my countdown to be accurate based on that date and not 40 wks. I don't want to change my actual due date cause then all the information I read will be 2 weeks ahead...
