Feature question for the pro version of the plugin

Hello, on the pro version of the plugin is it possible to block out specific times in the future? These times will not be reocurring will just be one-off times.

Like for example today is a monday and I want to block 2:00pm to 3:00pm today because there is a scheduled training time for the staff. I will block 2:00pm – 3:00pm but tomorrow and the days going forward this time will be open
