Have project to dos assigned to company show up for all users in their multi-project calendar

Based on support ticket I submitted - photos for extra context available here : #29521

I can create project to dos that are assigned to my own company via the teamlink option, and this will make it so that those project to dos show up in the employees alert lists but not in their to do calendars. I had a client ask if I could utilize the all projects calendar to show open tasks, which could also be seen by people in the field. As far as I know, checklists are closed to just within the individual project and to dos are typically limited to a single assigned person.
