Exempt reservation type from prime time hours within 24 hours

I would like a way to allows a reservation type that is following a prime time schedule to be exempted from this schedule 24 hours ahead. I thought I had found it with the "bypass restrictions if time is x hours out", but I think that might be just for reservations restrictions and the thing I am talking about (Drilling - Rebounder) is not included in the 'booking restrictions' because our restrictions are based on 'bookings per day' and we don't want this type included. Is there any other way to allow them on short notice (24 hours) to be able to book the rebounder during prime time if space is available? Thanks
