Custom notes on bookly default calendar

Hi, admin/staff can use the Internal note field to add notes and create Custom Appointments to mark some slots as booked. You can use Staff Cabinet (Add-on) if you want to allow your employees to manage their bookings without the need for access to the WordPress admin panel.

Ok, thank you.

But if we want to promote that some timeslots/dates has coupons can we mark some timeslots with such notes on public calendars ?

Hi, currently, this is not supported.
