@Doris6 This idea has been proposed under Host Voice, I believe. That is where a host suggestion with sufficient host support can be forwarded to the Air BNB team for consideration. Meanwhile, how you handle this is dependent on your market place. The current system does not allow for date specific cancellation policies. For me, I have several highly desireable weekends related to music festivals that guests book a year in advance. I go to a strict cancellation until these dates are booked and then I go back to a moderate. I do that because I want serious guests, not browsers. Good luck
