I'm using the appointment+ booking form and I have a couple

HI, I'm using the appointment+ booking form and I have a couple of questions.

1 - Is there any way that I can set the main calendar to display the calendar. I don't want to all any booking from the front-end. Only the admin should be allowed to create a booking.

2- is it possible to have a custom icon within the calendar depending on the service type? As we have different types we would want to represent these so that the suer can easily distinguish between the different services available.

Thanks in advance!
