Customization of Wordpress Booking Calendar

Hello: We have purchased the MultiUser version of Wordpress Booking Calendar. [login to view URL] - This is fully customized with ONE exception that we need help with. (1) Need the ability to have a calendar day AND TIME close off when 2 reservations per time have been booked. Here is a page to review: [login to view URL]~mcfuncom/location-1/ Details: - A user can book 1 day and a party time. - Currently, you can book X amount per day BUT not per day and time. - We need the calendar to close of a day and drop down time if 2 reservations have been made for the specific time. Example: I choose April 26 at 10am - 11:15. Another User chooses April 26 at 10am - 11:15; The form should close off ONLY 10-11:45 but the rest of the day and times available remain open. This is the ONLY functionality that we need. Please feel free to ask question to ensure that you understand the scope of the project.
