Inquiries about multi-select and select settings

Hello, I am writing this post because I have a few questions while currently using the plugin.
I use multi-select and select to select a reservation time. Can I make the selected reservation time not visible? For example, if I make a reservation for 3 and 5 o’clock, I want the 3 and 5 o’clock fields to disappear to prevent others from making reservations. Is it possible to configure this part? It’s urgent, so please check it quickly. ㅠㅠ Or is there a different way to use it? When selecting a reservation time, the selected reservation time should not be selected or visible. Please check. Thank you 🙂
