You can now set availability rules for Appointment Services per board. Boards are where you assign Staff, Venues and Services.
You may want a service only bookable certain hours on one board and bookable different hours on another. Or the same for both. Either way, here's how you set this up.
Click Appointments > Boards > select a board
Select Services > locate the service > click the dropdown menu to the right > click Availability times.
Click 'Add availability rule' > set the service's availability
As an example, the availability rule below:
is valid immediately (meaning this new schedule is bookable immediately)
allows this service to be booked from 7am - 1pm, on Mondays, Tuesdays Wednesdays
