PowerBI record date

Hi all im wondering if theres a way in powerbi to write a function that can record dates and log them below is an example i have where i have a date column that just generates todays date whenever the "install status" column reads "installed". the only problem is that with this method i can only generate todays date each time one of the install status's switches. which is why im trying to see if theres a record function or a way to log whatever value shows up in the install date column so that i can show a varity of dates and not just todays date
