How can I modify the shortcode in appointments+ to enable you to check service availability in a sid


I understand there is a limitation when using the calendar as a widget, that is, you can’t select a service to see if it has a free slot in the calendar. I know I can use short code in a text widget but I want a cross between the calendar widget and shortcode operation. What I really want is to enter shortcode for the services and calendar but when a client clicks on a free time slot they are taken to the booking page. Can you help me to do this please?
