Currently, round-robin calendars are only true round-robin calendars from a functionality point-of-view. From a personalization point-of-view, they stink.
Once it is determined whose calendar should appear for the contact, you should be able to display the appropriate team member's avatar or custom set image, rather than using the company avatar or a single custom set image for all team members.
The same goes for the meeting link that gets sent out in the invite once a meeting is booked. So while the round-robin calendar uses the specific team members calendar availability, it does not let each member use their own link/room for the meeting.
So... if Team Member A books a meeting for 1pm, Team Member B can't book a meeting for the same time even if they are available, because the meeting link/room will be in use by team member A!
The bottom line is this, in order for round-robin calendars to be true round-robin calendars both in function and personalization, we need to be able to edit the scheduling page and features for each team member included on a round-robin calendar so that it displays each member's scheduling page/calendar, rather than just displaying the same calendar for everyone and pulling in the specific team member's availability.
