You need to be on the PRO or Ultimate plan with the "Google Calendar" and / or "Outlook Calendar" feature enabled.
You can pull multiple calendars in WeekPlan and select one to push the events / tasks in a Google or Outlook Calendar.
By default tasks coming from calendar for which PUSH enabled, when edited in WeekPlan changes will goes to calendar but events / tasks coming from other pulled calendars when edited remains in WeekPlan.
If you enable setting "Push edited tasks from other calendars (Google / Outlook Calendar Synchronization)" in Workspace Settings page, all the events/tasks from pulled calendar when edited in WeekPlan will go to pushed calendar.
