Auto Locking a Dropdown in a Form

edited 12/09/19 in Smartsheet Basics

We are trying to create a form or update request (not sure which would be best) that allows external users to select a date and time from a dropdown list and when one person has selected that time it then doesn't allow another person to select that time and disables it as an option. Is this possible with some sort of auto locking of a dropdown option when it has already been selected?
