Calendar Software / Workfront Integration

Hello, Does anyone have a recommendation for calendar software that could seamlessly integrate with Workfront? We have multiple calendars throughout our organization, on a variety of platforms. We're looking to set up a "single source of truth" in Workfront for Marketing and Communications teams - m any of our current calendars are duplicative and items often have to be logged multiple times in different formats. The right software would be highly graphic, and customizable for different users/teams as regards views, permissions, notifications, and roles/responsibilities. Would welcome any suggestions. Thank you! Bill Harnett
