We use Instant Booker to allow clients to book windows of 2 hours, and use different Meeting Types to define when they can book, typically between 8am and 4pm. We want to restrict the start times of these 2 hour events to only be multiples of 2: there is an available slot at 8, and then at 10, and then at 12, etc. We do not want a client to be able to book a 2 hour window that spans 9-11, for example. This functionality would correspond to setting an Availability Increment of 2 hours, but the Availability Increment parameter maxes out at 1 hour. I suggest allowing arbitrarily large Availability Increments. Thank you!
