See multiple assignees in the Calendar view

Currently, when viewing To-Dos (I assume any other item too) on the Calendar view under releases, you cannot see multiple assignees, only the first. We often assign to-dos to multiple people as they need to complete the same activity but if they are viewing from the calendar view then they do not realize that the task is assigned to them as well. I've tried to add multiple rows for assignee on the 'customize record card' but it just shows up as the first assignee multiple times. We are currently using Pivots under roadmap instead but that is not as user friendly of a view. I've put 'needed by yesterday' only because I believe this should be a pretty simple fix.
