More than one worked in a [app_monthly_schedule]

On the Appointments booking page, need to show only the calendar and Confirm button, with two service provider and one service.

Shortcode used on a page:
[app_monthly_schedule service = “1”]
[app_pagination month = "1"]
[app_confirmation]

The shortcodes were working great until Exceptional Working days needed to be added. With this combination, Exceptional Working days were shown as red color (impossible to book). After adding worker attribute the Exceptional Working days are showing. But it can be booked only for one service provider.

Is it possible to have two service provider in worker="1,2" attribute, so the slots will be booked to any available service provider?
