Can I auto-create a subsequent record when adding a new record, given certain data driven circumstances?

I'm using a calendar report to allow customers to reserve equipment. Each equipment has it's own calendar report, and customers can see what time slots are booked (or available) during the day/week and then use the "ADD" link in the calendar report to book time for themselves. One particular piece of equipment needs an hour downtime following a reservation when it is used for specific purpose, for cleaning/preparation. So, I was wonder if a new record could be automatically created to block off an hour following the reservation for that specific equipment when that specific purpose is selected on the Add form.
