Feature request for length of luteal phase

We should be able to tell the app what our average luteal phase is so that it can accurately predict cycle lengths and when a period is due to arrive. I have a 10-11 day LP and the app always predicts 14 so the data is always wrong. Today when I logged the start of my period, the app event went back and changed my fertile window to match 14 days back when I entered a positive opk 11 days ago! Now I had to go write in the note that I ovulated so if I’m looking back at my calendars I know what actually happened. Other apps ask for LP length for accuracy and Glow should too!
