Availability Calendar could indicate same day changeover

Would other owners like the Availability Calendar to indicate "same day changeovers"? Just a diagonal line across the day would be enough. Currently, for example, a 15 day booking looks just like a 7 day guest leaving and an 8 day guest arriving on the same day. This would make it easy to spot at a glance which days we have do something like make sure the cleaners haven't forgotten that they're booked.
