Appointment Field: Is it possible to keep users from selecting a date in the future?

I have created a form for our boat sharing program. I want to somehow restrict how many bookings members can make at a time. I am trying to avoid certain members booking in advance so others won't be able to book. Is that possible with your new Appointment form?

I think the "Rolling Days" will allow you to do this, for example, if you set this option to 3 the users will be able to book a date only up to 3 days in the future, here is an example:

As you can see you have only 3 days available to select. 

You will find the above mentioned option on the field settings under the limits tab.

Kindly give it a try and let us know if you have any questions.
