Appointment field: How to block a time slot from specific date?

I've made a tattoo booking form for people to book a tattoo appointment, and I've set specific days with 2 time slots. When people book with the form, it removes the appointment time for that day of course, but some people need to make appointments with me with direct messaging, and so the date on the form stays available. I'd like these times to be unavailable for new people using the form, but I can't figure out how to block off a specific time without removing the whole day. How can I do this?

Hi impigeon,

Thanks for reaching out to Jotform Support. Unfortunately, the feature you're looking for to block a specific time isn't currently available at Jotform. I've escalated this to our developers as a feature request, but when or if it's developed depends on their workload, how viable it is, and how many other users also request it. If there are any updates, we’ll circle back to this thread and let you know.

I would suggest you send the form URL to customers who are scheduling appointments via direct message so they can fill up the form.

Thanks for your patience and understanding, we appreciate it.

Hello Shoaib,
