It would be great to have a feature where we can put a "hold" in the calendar for a guest, but without blocking off the calendar. For mid-term rentals, this would be helpful to us as some people book far in advance and it would be best to place them in a unit that works better for our vacancy windows. Basically, we want them "on the calendar" without blocking any calendar dates for others to book, as the individual is flexible on the unit we place them in.
