Appointments + [app service] on 2 pages

I want use appointments + in two differents pages, with differents service on each pages (10 on one, and 5 on the second), but i want only one calendar, when someone take an appointments in the 1st page at 12h, i want nobody can take an appointment in the second pages.
I just want use a shortcode with a list defined of service like : [app_services service:"1,2,3"
], but it's not possible ...
I try to give one different service provider for the differents service, but the callendar don't syncronise .
If someone have a solution ?
