Team calendar - Agenda and Tasks.

Hello! We are working with a sale manager that needs to be able to see who the assigned user is on the Agenda and Task screens for the Team calendar. They are currently using CRM 2017 R3.

Is it possible to add a column to the Team Agenda and Task lists? I am not able to find anywhere in the forum or guide where this might be possible. I also could not locate screens in the system to do this. Hoping I can find a way to add the column as the list is currently useless to him without that information.

Any assistance would be greatly appreciated. Thank you!
